The function of feedforward controller in improving system tracking performance is analyzed and a method of designing wideband feedforward controller based on frequency domain model parameter identification is proposed by using sinusoidal signal amplitude and phase adaptive control principle. The system simulation shows that the controller design It can improve the system’s frequency and time domain characteristics. Feedforward controller characteristic parameters can be tested on-line, reducing the impact of model estimation uncertainty.
