Linear Quadratic Tracking in Fault Tolerant Control of DC motor in the presence of actuator faults

Abstract

This paper discusses the development of a fault tolerant control (FTC) of permanent magnet DC (PMDC) motor system. Multiple Models Switching and Tuning (MMST) is used along with Linear Quadratic Tracking (LQT) so that system output is able to track a reference signal optimally. This method is applied to the PMDC motor model subjected to actuator faults and the simulation results are presented.
