- AD4820 model predictive control case example
- We are excited to introduce an application for batch reactor temperature control that was developed using the model predictive control technologies of A&D Company, Ltd.’s (A&D) AD4820.
- The application was developed by JGC Corporation. JGC Corporation has annual sales of 608,529 million Japanese yen and approximately 2,020 employees. JGC has primarily been involved in providing consulting, planning, basic and detailed design, materials and equipment procurement, construction, commissioning, operation and maintenance services for various plants and facilities.

- Model Predictive Control (MPC) is a process technology that was invented based on principles proposed by Dr. Jacques Richalet in the latter half of the 1960’s. In order to predict future behavior, multiple computation processes are required. Since the 1980’s, MPC has primarily been used in the petrochemistry industry and the equipment necessary for MPC was extremely expensive. However, after the processing speed increased dramatically for the comparatively less expensive CPU type controllers which have gained reception recently, the price range for MPC instruments has decreased―making it possible to use them for more general applications.
- A&D’s AD4820 is a device that makes MPC possible and there is no similar device on the market that is more compact.
- At present, PID controllers are the most widely used controllers for general control procedures. However, once phenomena occur, PID control systems overshoot and undershoot when performing corrections, and they cannot execute extremely precise controls.
- The application that we are introducing here today makes possible MPC for batch reactor temperature control. It was developed by Mr. Yoshikazu Noguchi and Mr. Masanori Kobari from JGC, who utilized A&D’s AD4820 hardware and MATLAB Simulink, The MathWorks, Inc. development software, to perform extremely precise temperature measurements.
