Permanent Magnet DC Motor Sliding Mode Control System

Abstract

In this paper a sliding mode controller (SMC) is designed for a permanent magnet direct current (PMDC) motor to enhance the motor performance in the presence of unwanted uncertainties. Both the electrical and mechanical signals are used as the inputs to the SMC. The complete motor control system is simulated on a personal computer with different design parameters and desirable system performance is obtained. The experimental implementation of the motor control system by a floating point DSP is also presented. The test results confirm the simulation results and validate the proposed motor control system for high performance applications.
