Article Preview

The paper presents a dual closed-loop vector control system based on dsPIC30F6010A for asynchronous motor which is a multi-variables, nonlinear, strong coupling and time-varying system and is difficult to determine precise mathematical model because of changes in motor parameters and load fluctuations in factors. Torque current differential Speed estimation method proposed and experiment results proved this method has satisfactory dynamic response, anti-interference ability and robustness.
