Design of Fuzzy Sliding Mode Controller for Bullet-Borne Permanent Magnet Synchronous Motor
A surface mounted vector control model for missile borne permanent magnet synchronous motor servo control system was established,and a fuzzy sliding mode controller based on variable exponential convergence rate was designed.This method introduces the idea of fuzzy control into the sliding mode control strategy,and dynamically adjusts the relevant parameters of the sliding mode approaching law through a fuzzy controller.This method significantly improves the response speed of the system and effectively weakens the chattering caused by sliding mode control.Finally,the method was simulated on the MATLAB/Simulink platform.From the experimental results,it can be seen that compared to traditional PI controllers,the fuzzy sliding mode control algorithm proposed in this paper has significant advantages in improving system response speed and exhibits strong robustness,fully meeting the strict requirements of the system for control accuracy.
