| 摘 要： | 为了提高无刷直流电机(BLDCM)控制的抗负载扰动和快速响应能力,利用滑模变结构原理设计了一种指数趋近律的滑模变结构控制策略,并对该控制策略的可行性进行理论分析。通过设计BLDCM控制系统的速度环节,使控制性能得到很大改善。仿真试验表明,该控制策略具有响应速度快、无超调、抗负载扰动能力强等优点,提高了BLDCM的鲁棒性,从而验证了指数趋近律的滑模变结构控制策略的有效性。

| Abstract: | In order to improve the ability of inhibition disturbances and quick response with brushless DC motor(BLDCM),a strategy of sliding mode control with exponential reaching law,and analysis of this control strategy fea-sibility was designed.Through the design of BLDCM speed control system,the control performance was improved greatly.The simulation results showed that the control strategy has good performance with fast response,no over-shoot,ability of strong inhibition disturbances,and greatly improved the rob... |
