| Abstract: | The generalized predictive control algorithm is selected for the process. The single-step generalized predictive controller based on S7-200 typical one-order production PLC has been designed. This algorithm is carried out by experiments in a liquid level control system on JWS-6/3- 4 process control equipment. The experiment has shown that this system can be controlled high accurately. The error is lower than 5 ram. It has run stably. The technology and method adopted in the system is practical and worthy being spread. |
