【Abstract】 The speed adjusting system with field weakening with voltage feedforward, current closed negative feedback and speed closed loop was designed by adopting digital signal processor (DSP). According to the special requirements of controlled motor and hardware configuration of DSP controller, the particular control strategy and the implementation were expatiated. By adding digital filter and watch dog technic, the immunity performance of the system was upgraded. Experiments prove that the control system features high reliability, simpler construction and higher stability.更多还原
