A Novel Closed-Loop Time-Delayed Filter for Unstable System

Abstract:

Aiming to improve the stability dynamic performance of the oscillating system, an internal closed-loop time-delayed filter with negative pulse is designed. To make the unstable system into stable, a reasonable time delay is introduced within the feedback control system, based on optimization theory to design the delay filter parameters. Matlab/SIMULINK simulation software is used on system performance analysis. Simulation results show that the designed internal closed-loop time-delayed filter can effectively improve the system stability, but also inhibit the high-frequency noise, with a strong anti-interference ability.
