Robust design of motor PWM control using modeling and simulation

Abstract

A robust design method is developed for PulseWidth Modulation (PWM) motor speed control. A first principle model for DC permanent magnetic motor is used to build a Simulink model for simulation and analysis. Based on the simulation result, the main factors that contributed to the average speed variation are identified using Design of Experiment (DOE). A robust solution is derived to reduce the average speed control variation using Response Surface Method (RSM). The robustness of the new design is verified using the simulation model. © Springer Science+Business Media B.V. 2009.
