Design of Servo Motor Control Strategy Based on Fuzzy PID
Traditional PID,as the simplest closed-loop control strategy,is widely used in industrial control processes.However,because it is vulnerable to interference factors and is not suitable for nonlinear system control,its application scenarios are limited.In order to achieve better control effect on nonlinear system in the interference environment,this paper uses fuzzy PID to design the control strategy of servo motor,establishes the control loop of traditional PID and fuzzy PID through MATLAB/Simulik,and compares their control performance.The results show that the response speed of fuzzy PID is superior to traditional PID,and the overshoot is small.To verify the effectiveness of fuzzy PID application,this article establishes a testing platform with the MI-7016 data acquisition instrument as the core and using speed and displacement sensors for detection.The results show that the fuzzy PID has a good control effect on the motor,and the displacement error of the end clamp of the device is less than±1%,which meets the usage requirements.
