Iterative learning control implement for permanent magnet liner motor vector model

Permanent magnet linear synchronous motor working principle and the vector control model are analysed, control scheme adopts double closed loop, speed loop is composed of PI controller, current hysteresis tracking PWM control technology is adopted in the current loop. According to the modular modeling idea, the control system is divided into various independent function modules, including: permanent magnet synchronous linear motor body module, vector control module, coordinate transformation module, hysteresis current control module, PWM voltage inverter module, the speed control module, through the organic combination of these function modules, build the simulation model of vector control system of permanent-magnet linear synchronous motor in Matlab/Simulink, and the realization of simulation application control algorithm for double loop in precision motion control of permanent magnet synchronous linear motor. In the experiment research of ILC, DSP TMSF2812 and Elmo driver are used to construct the three-loops control system of PMLSM. Through programming control algorithm to the DSP and with some debugging of the parameters, we finally get an ideal result. It is proved that in some field requiring repeat movement, ILC have a better control performance than PID, and that the debugging of ILC is more quick and more simple.
