Abstract A novel design method of the PI controller is proposed in this paper.The controller lumps various known and unknown quantities that affect the system performance into a total disturbance,simplifies the system model,and then uses the integrator as an observer to realize total disturbance estimation and rejection.The parameters in the novel PI controller have simple relationship with system performance,and are easy to tune.With the input derivative feedforward (IDF)used in the novel PI controller,better performance of tracking the continuous varying input can be obtained.The IDF is just a differentiator irrelative to the parameters of the permanent magnetic synchronous motor (PMSM),which further simplifies the controller design process.The discrete fastest tracking differentiator (DFTD)is used to diminish the overshoot in the step response,which improves the parameter insensitivity of the system at the same time.Extensive experiments are performed to verify the validity of the proposed algorithm.

Key words： Permanent magnetic synchronous motor PI controller parameter tunning continuously varying input input derivative feedforward transient profile
