Design of Controller for Three Phase Motor Using TMS320F28335

Float DSP TMS320F28335 was used to control three phase motor.For its faster speed and more accurate calculation than TMS320F2407 and TMS320F2812,it was more suitable for complex control strategy.Detailed functions and hardware circuits were introduced.The system can work by using a rotary encoder to have speed feedback or using estimated speed.The system is proved to be stable and robust.
