Design of Motor Controller Based on TMS320F28335 Digital Signal Processing Chip

Abstract

Aiming at the high-power permanent magnet synchronous motor (PMSM), the corresponding motor controller is developed. The vector control strategy with id=0 is adopted to establish the simulation model. The TMS320F28335 digital signal processing chip is used as the core to build the control, protection and drive circuit of the motor controller. Find the law of PID regulation through simulation. After the successful verification of the 0.75kW permanent magnet synchronous motor(PMSM), we carried out the experiment under the high power permanent magnet synchronous motor(PMSM) of 35kW. The simulation and experimental results show that the system has a fast speed response and can realize the control of the motor speed. The protection circuit also shows an effective protection for the motor.
