| 摘 要： | 直接转矩控制是一种新型的感应电动机控制方法,设计的关键是怎样选择适当的定子电压矢量来使定子磁链和转矩限制在它们的允许范围内.然而由于滞环控制器的特点,不论转矩偏差的大小均采取同样的开关策略,因此,在起动或给定转矩、给定定子磁链发生阶跃变化时的响应较缓慢和产生大的转矩脉动.用模糊控制器可以解决这个问题.仿真结果证明此方案可行.

| Abstract: | Direct torque control(DTC) is a new method of induction motor control.The key issue of the DTC is the strategy of selecting proper stator voltage vectors to force stator flux and developed torque within a prescribed band.Due to the nature of hysteresis control adapted on DTC,there is no difference in control action between a large torque error and small one.Thus it may produce big torque ropple.A fuzzy controller has been introduced to deal with this issue.The simulation results verifies the new control strategy. |
