摘要：
In this paper, the q-d axis currents in the vector control of permanent magnet synchronous linear motor are coupled with each other, which affects the control performance of the motor. By establishing a model of permanent magnet synchronous linear motor and analyzing the coupling reasons, a feedforward decoupling method is proposed to realize the current control of motor. On this basis, an anti-saturation integration algorithm is proposed to solve the saturation integral problem in motor speed-loop control. The system simulation results show that the decoupling current control performance is significantly improved, and the speed response performance is good.
