摘　　要：提出一种改进型无差拍预测电流控制方法与改进型滑模控制方法结合的控制策略。基于永磁同步电机的数学模型,构建电流内环控制算法,设计扩张状态观测器,解决无差拍预测电流控制因参数扰动及模型失配导致的电流误差问题。速度外环设计一种超局部模型滑模控制器,设计滑模扰动观测器削弱滑模抖振。仿真结果证明,结合后的控制方法有效提高了电机暂、稳态性能,提升了系统抗干扰能力、鲁棒性及响应速度。A control strategy was proposed combining an improved deadbeat prediction current control method and an improved sliding mode control method.Based on the mathematical model of permanent magnet synchronous motor(PMSM),the current inner loop control algorithm was constructed,and the extended state observer was designed to solve the current error problem caused by parameter disturbance and model mismatch of the deadbeat prediction current control(DPCC).A hyper-local model sliding mode controller was designed in the velocity outer loop,and a sliding mode disturbance observer was designed to weaken the sliding mode jitter.The simulation results show that the combined control method effectively improved the temporary and steady-state performance of the motor,and improved the anti-interference ability,robustness and response speed of the system.
