Efpt Process Experimental Device Modeling And Control

The objective of this paper is to establish a process control experimental system, which should be easily operated and make the control policy implement conveniently.In this paper, a computer monitor and a control system is developed based on the parameter fuzzy self-tuning PID control algorithm for the EFPT process control experiment equipment.A kind of parameter fuzzy self-tuning PID control algorithm is presented which combined the traditional PID algorithm and fuzzy algorithm. For the boiler temperature system, firstly a mathematic model was built from the step-response curve, and then the simulations have been done to compare with the PID control and parameter fuzzy self-tuning PID control separately by the simulink platform of Matlab. From the result the correctness and feasibility of parameter fuzzy self-tuning PID control was demonstrated. Then the parameter fuzzy self-tuning PID algorithm was used in the EFPT process control experiment equipment. From the curve of experiment, the feature of the lighter exceeding, no shaking, good stability, short time to reach the stable state, little error of stable state can be seen. So its dynamic and static characteristic is superior. Therefore it has verified that the feasibility of using parameter fuzzy self-tuning PID control in the temperature control system.Finally, the temperature control of parameter fuzzy self-tuning PID was implemented on a single chip microcomputer. The parameter fuzzy self-tuning PID control was applied to the temperature control system of EFPT process control experimental equipment, and it can improve the system's control performance obviously.
