摘要

This article presents a novel robust control technique for application to PWM AC choppers with ability of generating high quality sinusoidal waveforms with adjustable amplitudes over a wide range control. For this purpose a deadbeat based digital controller has been developed to perform tight closed-loop control of the AC chopper. This controller is based on the generalized predictive control approach. The proposed controller presents the advantages of allowing a very fast transient response and compensating effectively load disturbance and nonlinear loads effects. Computer simulations are performed to investigate the proposed controller performances. The simulation analysis of the PWM AC chopper has been carried out in detail. The simulation results show that the designed controller has a good dynamic behavior, a good rejection of impact load disturbance and very robust. Then computer results have been validated experimentally.
