摘　　要：针对异步电机实际运行的耦合性和抖振等问题,提出了一种基于滑模变结构自抗扰控制的复合控制策略。首先,建立矢量控制下的异步电机数学模型,通过选择异步电机转速为状态变量,利用自抗扰技术中LESO的补偿扰动的思想设计了异步电机转速环的双闭环SMLADRC控制器,通过证明LESO的收敛性和分析SMC的系统稳定性,说明上述控制器既保留了传统滑模的强鲁棒性,又利用自抗扰的优势,有效地削弱了电机抖振问题。通过数值仿真验证了上述控制策略的可行性与正确性。Aiming at the problems of coupling and chattering in the actual operation of induction motor,a composite control strategy based on sliding mode variable structure active disturbance rejection control is proposed.Firstly,the mathematical model of asynchronous motor under vector control was established.By selecting reasonable state variables and using the idea of disturbance compensation in active disturbance rejection technology,the SMADRC controller of asynchronous motor speed loop was designed.The controller not only retains the strong robustness of traditional sliding mode,but also effectively weakens the motor chattering problem through compensation.Finally,the feasibility and correctness of the control strategy were verified by numerical simulation.
