摘　　要：通过分析无刷直流电机控制系统,基于滑模变结构的原理设计出了采用指数趋近率的滑模变结构控制策略,将该控制策略应用于无刷直流电机的调速系统中,并通过仿真与实验验证了系统的可行性。该方法设计算法简单,容易实现,对比传统的六步控制方法,滑模变结构策略的响应速度更快,系统对外部的扰动及参数的摄动影响小,鲁棒性强,增强了控制系统的动态性能和稳定性能。Through the analysis of the brushless DC motor control system,the sliding mode variable structure control strategy with exponential reaching rate is designed by using the principle of sliding mode variable structure.The control strategy is applied to the speed control system of brushless DC motor,and the feasibility of the system is verified by simulation and experiment.The algorithm of this method is simple and easy to implement.Compared with the traditional six-step control method,the sliding mode variable structure strategy has faster response speed,less influence on external disturbance and parameter perturbation,and strong robustness,which enhances the dynamic performance and stability of the control system.
