Abstract

In this study, the speed control of a DC motor with input delay and external disturbance is investigated. A delay‐dependent memory state feedback robust predictor‐based H∞ controller that formerly has presented is utilized. Sufficient LMIs conditions provide the stabilizing gain of the predictor‐based controller. The first‐order model of a DC motor has been studied previously using PID and STA (super twisting algorithm) methods. However, in this paper, the delay‐dependent robust H∞ controller is used on both the first and second orders of the DC motor. Finally, the predictor‐based H∞ controller is compared to the PID controller and the common H∞ controller as well. The simulation results show that the proposed method has been more useful and efficient.
