Special Issue Information

Dear Colleagues,

The synergy between model predictive control (MPC) and evolving sensor technologies represents a new era of intelligent control. This Special Issue, “Model Predictive Control: Advances in Sensor Technologies and Applications”, explores the multi-faceted relationship between these two fields.

The depth of sensor feedback loops, revealing the crucial role of sensors in MPC, highlights their integral function in feedback control. The fusion of different sensor data provides a broader perspective on MPC and enriches decision-making processes. In the era of data overload, techniques to control inconsistent or unreliable sensor data are becoming increasingly important in MPC. Moreover, the real-time applicability of MPC, when tested via the integration of wireless sensor networks, is both a challenge and a breakthrough. The introduction of soft sensors that can either complement or potentially replace traditional hardware is exciting. Finally, the transformative impact of self-calibrating sensors that redefine the adaptability of MPC is being explored.

This Special Issue aims to shed light on these intersections and foster a deeper understanding of this transformative technology. The authors' insights, research and innovations are invaluable to this discourse.

You may choose our Joint Special Issue in Automation.

Yours sincerely,
Prof. Dr. Simon Tomažič
Guest Editor

Existing control strategies, such as Real-time Optimization (RTO), Dynamic Real-time Optimization (DRTO), and Economic Model Predictive Control (EMPC) cannot enable optimal operation and control behavior in an optimal fashion. This work proposes a novel control strategy, named the efficiency-oriented model predictive control (MPC), which can fully realize the potential of the optimization margin to improve the global process performance of the whole system. The ideas of optimization margin and optimization efficiency are first proposed to measure the superiority of the control strategy. Our new efficiency-oriented MPC innovatively uses a nested optimization structure to optimize the optimization margin directly online. To realize the computation, a Periodic Approximation technique is proposed, and an Efficiency-Oriented MPC Type I is constructed based on the Periodic Approximation. In order to alleviate the strict constraint of Efficiency-Oriented MPC Type I, the zone-control-based optimization concept is used to construct an Efficiency-Oriented MPC Type II. These two well-designed efficiency-oriented controllers were compared with other control strategies over a Continuous Stirred Tank Reactor (CSTR) application. The simulation results show that the proposed control strategy can generate superior closed-loop process performance, for example, and the Efficiency-Oriented MPC Type I can obtain 7.11% higher profits than those of other control strategies; the effectiveness of the efficiency-oriented MPC was, thereby, demonstrated.

This research proposes advanced model-based control strategies for a countercurrent flow plate heat exchanger in a virtual environment. A virtual environment with visual and auditory effects is designed, which requires a mathematical model describing the real dynamics of the process; this allows parallel fluid movement in different directions with hot and cold temperatures at the outlet, incorporating control monitoring interfaces as communication links between the virtual heat exchanger and control applications. A multivariable and non-linear process like the plate and countercurrent flow heat exchanger requires analysis in the controller design; therefore, this work proposes and compares two control strategies to identify the best-performing one. The first controller is based on the inverse model of the plant, with linear algebra techniques and numerical methods; the second controller is a model predictive control (MPC), which presents optimal control actions that minimize the steady-state errors and aggressive variations in the actuators, respecting the temperature constraints and the operating limits, incorporating a predictive model of the plant. The controllers are tested for different setpoint changes and disturbances, determining that they are not overshot and that the MPC controller has the shortest settling time and lowest steady-state error.

When conventional delivery vehicles are driven over complex terrain, large vibrations can seriously affect vehicle-loaded equipment and cargo. Semi-active vehicle-mounted vibration isolation control based on road preview can improve the stability of loaded cargo and instruments by enabling them to have lower vertical acceleration. A combined dynamic model including a vehicle and platform is developed first. In order to obtain a non-linear relationship between damping force and input current, a continuous damping control damper model is developed, and the corresponding external characteristic tests are carried out. Because some conventional control algorithms cannot handle complex constraints and preview information, a model predictive control algorithm based on forward road preview and input constraints is designed. Finally, simulations and real tests of the whole vehicle vibration environment are carried out. The results show that the proposed model predictive control based on road preview can effectively improve vibration isolation performance of the vehicle-mounted platform. Full article

Abstract: This research proposes advanced model-based control strategies for a Countercurrent Flow Plate Heat Exchanger in a Virtual Environment. First, an immersive 3D virtual environment is designed with visual and auditory effects, where a mathematical model is required that describes the real dynamics of the process, allowing the movement of the fluid in parallel in different directions with hot and cold temperature at the out. Which changes dynamically with the variation of the temperature of the hot and cold input fluids, in addition, it includes interfaces for monitoring the control variables, links that allow communication between the virtual heat exchanger and the control applications. The Plate and Counter-Current Flow heat exchanger, being a multivariable and non-linear process, requires analysis in the design of the controller. In this context, this work proposes and compares two control strategies with the objective of identifying the best performance. The first controller is based on the inverse model of the plant in discrete time, with linear algebra techniques and numerical methods, the second controller applied is an MPC predictive control model, which presents optimal control actions, which minimizes state errors. stationary and aggressive variations of the actuators, respecting temperature restrictions and operating limits of the actuators, incorporating a predictive model of the plant that takes precedence over errors. Both controllers are tested at different set point changes and disturbances, determining that both do not present overshoot and that the MPC controller has a shorter establishment time and lower steady state error.
