In this paper,the characteristics of servo control tripe closed-loop speed regulation are analyzed,followed by an introduction to the features of fuzzy control and PI control.The fuzzy control principle is used to adjust the proportional,integral and differential parameters of traditional PI control online to form an intelligent PI controller.The setting is based on the current position and speed sampling feedback value of the antenna.The bases for tuning is simulated using MATLAB to obtain the results,and the simulation results are analyzed in time domain.
