Stabilization with the Idea of Notch Filter in Automatic Control System

Stabilization is one of the most significant step of automatic control system design. In this paper, we propose a stabilization method for linear time-invariant SISO systems from the view of signal processing. In this method, the complex plane is regarded as a frequency plane, and the control law to improve the stability of the system is designed with the idea of filtering, which has the advantages of intuitive design and easy adjustment. The feasibility of this method is proved by simulation, and the relationship between the design of control law and the dynamic characteristics of the system is analyzed.
