Output Feedback Control of Two-Time-Scale Permanent-Magnet DC Motor Using High-Gain Observers

Abstract

In this paper, we propose a methodology for implementing an output feedback control (OFC) strategy for a two-time-scale nonlinear system. A permanent-magnet DC motor model is utilized. We estimated the states using a high-gain observer for a two-time-scale nonlinear system. The results demonstrate the robustness and efficacy of the suggested OFC technique. Furthermore, the output feedback control approach exhibits robustness to parametric uncertainties, thereby making it feasible for practical implementation in a two-time-scale nonlinear system.
