摘要
针对弹载永磁同步电机伺服控制系统,建立了表贴式弹载永磁同步电机矢量控制模型,设计了基于变指数趋近率的模糊滑模控制器.该方法将模糊控制思想引入滑模控制策略,通过模糊控制器动态调整滑模趋近律的相关参数,显著提升了系统的响应速度,同时有效削弱了滑模控制引起的抖振.最后,在MATLAB/Simulink平台对该方法进行了仿真.由实验结果可知,与传统的PI控制器相比,所提模糊滑模控制算法在提升系统响应速度方面具有显著优势,且展现出了较强的鲁棒性,完全能够满足系统对控制精度的严苛要求.
Abstract
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.
