| Title: | Control of PWM inverter using a discrete-time sliding mode controller | Authors: | Wong, LK Leung, FHF Tam, PKS |
Issue Date: | 1999 | Source: | PEDS'99 : proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems : 27-29 July 1999, Hong Kong, p. 947-950 | Abstract: | PWM inverters are widely used in UPS systems and driving induction motors. They give AC sinusoidal voltage under linear or non-linear loads which is a basic tracking control problem. Since the duty cycle of a PWM inverter is unchanged within one switching period, inverters are very suitable to be represented by discrete-time state equations. A discrete-time sliding-mode controller based on an improved reaching condition has been proposed by Gao et. al. This paper will apply this controller to control PWM inverters with linear and non-linear loads. It is shown that good output responses are obtained in both cases. | Keywords: | Computer simulation Discrete time control systems Electric control equipment Electric drives Electric loads Electric potential Nonlinear control systems Pulse width modulation Switching |
