Study And Development For GRP Wined Control System

The GRP Wined system is equipment that is product aquarium depositor and pipeline. The generally GRP Wined system is mechanical in our country. The mechanical GRP Wined system must frequent change machine gearing while product various specification production therefore product efficiency very low and not conventional operation. Furthermore, GRP Wined system can not adjustment continuously and therefore affect the technics of production due to the limitation of machine timing. Today, automation control system has been used and developed in all kinds of industry extensively. It is a trend that using the advance control system in the GRP Wined.The paper presents a three-loop control system for servo of the GRP Wined system; i.e., the system is consist of current loop, speed loop and position loop. Because the parameter of current loop is defmitude, which it is without appreciably altering in system running, and for the current loop is speediness, so we use the traditional PID control for the current loop. For the position loop designs, considers the exact orientation for overall system and insure the steady-state accuracy of complete system, we also use the PID control for the position loop. We use the fuzzy PID control arithmetic with self-reliant factor for the speed loop. Use fuzzy PID controller instead of original PID controller, we compare with PID control and fuzzy control. PID control is a consummate technique and used so extensively, but it must to know the exact model of system. Fuzzy control has the ability of adapt to the uncertainty of system, but response time of system has been effected. Thus, we select of merit of both and combine them to unity one. The result shows that the controller has robust for the changes of system parameter, variously of exterior circumstance and indefinitely system model.
