A H∞ robust controller design method based on feature configuration and H∞ filter is proposed. First, according to the dynamic performance requirements of the system time domain, the proper state feedback gain is designed by using the method of feature structure configuration. Then, the H∞ filter is designed and the state estimation is made. Finally, the appropriate weight function is added to construct the generalized object, Standard H∞ Robust Controller Design Problem for Coupling. This method can not only realize the dynamic response of the system in time domain, but also ensure the performance of the system in frequency domain and robust stability. Through the numerical simulation of cantilever vibration control, the validity of this method is further verified
