【Abstract】 In this paper, the method of analysing control systems with PWM amplifier based on the state-transition concept is discussed. The recurrence formulas and the flow diagram for computing program are given. As an example, the unit-step response of a digital servo-system with PWM amplifier is calculated, using the state-transition method. The advantage of the statetransition method is that it can describe the exact state of control systems with PWM amplifier.更多还原
