【Abstract】 Based on the state-transition concept, this paper presents the state-transition method of analysing control systems with PWM amplifier containing a nonlinear characteristic located at the output of the control system. The flow diagram for calculating program based on this method is also given to analyse the control system with a PWM amplifier containing backlash and the unit-step response of a nonlinear digital servo-system with a PWM amplifier is calculated as an example of using the state-transition method. The method presented in this paper is a pwerful engineering method of analysing control systems with a PWM amplifier containing backlash.更多还原
