Follow-up system control method based on fuzzy PID control

In order to solve the technical problem that a servo system does not have load change impact resistance due to a traditional PID (Proportion Integration Differentiation) controller, the invention provides a servo system control method based on fuzzy PID control, and the fuzzy PID control is applied to the servo system by adopting an embedded technology. By finding out the fuzzy relation between three parameters Kp, Ki and Kd output by PID and the error e and the error change ec, the error e and the error change ec are continuously detected in the operation of the servo system, when the load changes, the fuzzy PID control can carry out online modification on the three parameters according to the error and the error change on the basis of the fuzzy control principle, and the fuzzy PID control is realized. According to the fuzzy PID control method, the fuzzy PID control can be controlled to meet different requirements of different errors e and error changes ec on three parameters of the PID controller, so that w
