Aiming at the actual working condition requirements of a tracked omnidirectional platform, introduce the overall plan of the platform is introduce ,and select a brushless DC motor (BLDC) of 1000W is selected as the driven motor, the BLDC control principle and its control scheme are expounded. Based on DSP28335, the motor controller is designed, the hardware circuit is set up, and the software program is written and debugged. The double closed loop control scheme of speed and current is used.The speed of the motor is set to 3000rpm, and the phase voltage and current of the motor are measured.and the experiment shows that the controller has a stable performance, rapid response, and high practical application value, in the other hand it lays a foundation for the study of further control strategy.
