Improvement of control performances using hysteresis elementsapplied to motor drive system

摘要

It has been an important subject in automatic control to obtainquick response without overshoot for a step response and good robustnessagainst parameter variation of the control system. In this paper, theauthors suggest a method to improve these control characteristics by useof a hysteresis element, and then propose a model tracking system whichis composed of a nominal model including a hysteresis element and atracking system with a robust compensator. This proposal gives excellentperformance even under parameter variation
