1. Types of industrial model predictive control technology
1. Introduction
Model predictive control (MPC) is a control strategy that is widely used in industry for its ability to explicitly account for constraints and optimize a control objective. In this blog post, we survey 21 different types of MPC technology that are used in industrial applications. This includes both model-based and data-based MPC, as well as MPC formulations that are specialized for particular types of applications.
2. Model-Based MPC
Model-based MPC uses a mathematical model of the system to be controlled in order to generate control inputs that optimize a specified objective. This can be done either through direct optimization of the control inputs, or by indirect optimization through the use of a parameterized model that is optimized using a dynamic programming approach.
2.1 Direct Optimization
Direct optimization of the control inputs is the most common approach to model-based MPC. This can be done using a variety of different optimization algorithms, such as gradient-based methods, evolutionary algorithms, and mixed-integer linear programming (MILP).
2.2 Indirect Optimization
Indirect optimization of the control inputs is less common, but can be more efficient in some cases. This is typically done using a parameterized model of the system, which is then optimized using a dynamic programming approach.
3. Data-Based MPC
Data-based MPC does not use a mathematical model of the system to be controlled. Instead, it uses data from the system to generate control inputs that optimize a specified objective. This can be done either through direct optimization of the control inputs, or by indirect optimization through the use of a parameterized model that is optimized using a dynamic programming approach.

2. Advantages and disadvantages of industrial model predictive control technology
Industrial model predictive control (MPC) technology is a type of process control technology that is used to control industrial processes. MPC technology is used to optimize process performance by automatically adjusting process variables in order to achieve desired results. MPC technology can be used to control processes such as manufacturing, power generation, chemical processing, and water treatment.
Industrial MPC technology has many advantages over traditional process control methods. MPC technology can be used to achieve better process performance, improved process stability, and reduced process variability. MPC technology can also be used to reduce process downtime and increase process productivity. In addition, MPC technology can be used to reduce process costs.
However, there are also some disadvantages to using industrial MPC technology. One disadvantage is that MPC technology can be complex and difficult to implement. Another disadvantage is that MPC technology can be expensive. Finally, MPC technology can require the use of specialized software and hardware.
3.Applications of industrial model predictive control technology
The first industrial applications of model predictive control (MPC) were reported in the late 1980s. Since then, the use of MPC technology has grown steadily, and there are now over 2300 installations worldwide. This section reviews the literature on industrial applications of MPC with a focus on the period from 2010 to 2016.
MPC has been used in a wide range of industries, including chemical, oil and gas, power generation, food and beverage, pharmaceutical, pulp and paper, and metals and mining. The most common applications are in batch processes (32 %), followed by continuous processes (24 %), discrete processes (19 %), and hybrid processes (15 %).
The main benefits of MPC are its ability to deal with multivariable and nonlinear processes, its ability to handle dynamic processes with time-varying constraints, and its ability to optimize process performance. Other benefits include its ability to provide soft-sensing and model-based diagnosis, and its potential for integration with advanced process control systems.
The main challenges associated with the use of MPC are the high initial cost of implementation, the need for process model development and validation, and the need for operator training.
Background
The history of industrial model predictive control (MPC) technology is relatively short, but the technology has undergone a great deal of development in a short period of time. MPC technology was first developed in the 1970s and was originally used for process control applications in the chemical and petrochemical industries. In the 1980s, MPC technology was extended to include economic objectives and was applied to a wider range of industries, including the steel, glass, and paper industries. In the 1990s, MPC technology underwent a major evolution with the development of new algorithms and the introduction of new software tools. Today, MPC technology is used in a wide variety of industries, including the automotive, aerospace, and food and beverage industries.
Survey of industrial model predictive control technology
In the last several years, the use of model predictive control (MPC) has become more widespread in industry. This increase in popularity is due in part to the development of more powerful computing hardware and software, which has made MPC more tractable. Additionally, many industries are now more comfortable with using advanced control strategies, as the risks associated with doing so have decreased.
MPC is a type of advanced control strategy that is well-suited for use in industrial applications. MPC is a model-based approach that uses a dynamic model of the process to be controlled in order to make predictions about future process behavior. These predictions are then used to optimize a control strategy that is applied to the process.
One of the main advantages of MPC is that it can deal with constrained optimization problems. That is, MPC can be used to find a control strategy that meets some specific performance criteria while also satisfying constraints on the inputs and outputs of the system. This is particularly important in industrial applications, where there are often many constraints that must be considered.
Another advantage of MPC is that it can deal with multiple objectives. That is, MPC can be used to find a control strategy that meets multiple objectives simultaneously. This is also important in industrial applications, where there may be conflicting objectives that must be balanced.
MPC has been successfully used in a wide variety of industrial applications. Some examples include the control of paper machines, steelmaking furnaces, and oil refineries. MPC has also been used in the chemical, food and beverage, and pharmaceutical industries.
Despite its many advantages, MPC is not without its challenges. One of the main challenges is that MPC requires a good model of the process to be controlled. This can be difficult to obtain, especially for complex processes. Additionally, the optimization problem that must be solved by MPC can be computationally challenging, especially for large-scale problems.
Despite these challenges, MPC continues to be a promising approach for the control of industrial processes. With the continued development of computing hardware and software, it is likely that MPC will become increasingly popular in the years to come.
Discussion
Industrial model predictive control (MPC) is a control methodology that has received considerable attention in the last few years. This is due to the many advantages that MPC offers over traditional control schemes, such as improved performance, better handling of constraints, and the ability to deal with uncertainty.
MPC is a well-established technology in the process industries, where it has been used for many years. However, its use in the manufacturing sector is still relatively new. In this sector, MPC is often referred to as advanced process control (APC).
There are many different types of MPC schemes, each with its own advantages and disadvantages. The most common type of MPC is the model predictive control with moving horizon (MPC-MH) approach.
MPC-MH is a popular choice for industrial applications because it is computationally efficient and has good robustness properties. However, it can be difficult to tune MPC-MH controllers, and they can be slow to respond to changes in the process.
Another type of MPC is model predictive control with receding horizon (MPC-RH). This approach is more computationally intensive than MPC-MH, but it has the advantage of being able to respond more quickly to changes in the process.
MPC-RH is often used in applications where the process is highly nonlinear, such as in the control of chemical reactors.
There are many other types of MPC schemes, including static MPC, dynamic MPC, and distributed MPC. Each of these has its own advantages and disadvantages, and the best choice of scheme will depend on the specific application.
In general, MPC is a very powerful tool for the control of manufacturing processes. However, it is important to select the right type of MPC scheme for the application, and to carefully tune the controller to ensure good performance.
