【摘要】 ALA转子电机具有与普通电机不同的结构,但与普通电机一样,直接转矩控制也能改善其动态性能和抗干扰能力,同时也存在较大的电流、磁链和转矩脉动,逆变器开关频率不恒定,高频噪声等问题。为此,在速度PI调节器中采用了具有快速响应,对参数变化及扰动不灵敏的滑模变结构控制,仿真结果表明有很好的效果。更多还原

【Abstract】 Structure of ALA rotor motor is different from that of common motors,but direct torque control can change its dynamic performance and anti-interference as common motor.Also there are some problems with ALA rotor motor such as that current,magnetic flux linkage and torque pulsation are large,frequency of inverter switch is not stable,frequency noise is high.Therefore,in PI velocity controler a sliding mode variable structure control is applied,which is quick to response,insensitive to parameter variation and disturbance.Results of simulation shows fine effect.更多还原
