摘要
近几年来随着鲁棒控制的发展,线性时变参数(LPV)控制方法也得到了一定的发展,并在处理非线性系统上取得了一些成果。将LPV控制引入感应电机直接转矩控制,采用多胞技术设计了一LPV转子电流估计器,从而利用定子电流的测量值和转子电流的估计值计算定子磁链和电磁转矩,实现全速范围内定子磁链的有效测量。最后通过一仿真实例验证该方法的正确性和有效性。
In recent years linear parameter varying （LPV） control have been developed with the development of robust control, and obtained some achievements in non-linear systems control. The paper introduces LPV control to direct torque control of an induction motor, designs a LPV rotor current estimator by the polytope, calculates the stator flux and torque by the measured value of stator current and the estimation value of rotor current, and realizes the efficient measurement of the stator flux on the whole speed. The simulation resuits prove the correcteness and effectiveness of the LPV direct torque control.
