摘　　要：提出了一种新的感应电机模糊滑模转矩控制方法。该方法采用联合滑模观测和滑模控制的思想进行鲁棒方案的设计,变结构滑模控制提高了感应电机驱动器的鲁棒性,而模糊逻辑降低了转矩、定子电流、转子磁链的纹波波动,提高了驱动系统的稳态性能。计算机仿真结果表明,该控制方案拥有非常良好的动态特性、高精度的转矩跟踪能力、较强的鲁棒性和很好的抗外部负载扰动的能力。A novel fuzzy sliding-mode control method for torque control of induction motor was presented. The idea joins sliding mode observer and sliding mode control to robust program design.The sliding- mode control contributes to the robustness of induction motor drive, and the fuzzy logic improves the torque, flux, and current steady-state performance by reducing the ripple. Computer simulation results show that the proposed control scheme owns very good dynamic characteristics, high accuracy in torque tracking to reference signal and strong robustness to external load disturbances.
