Digital repetitive learning controller for three-phase CVCF PWM inverter

In this paper, a plug-in digital repetitive learning control scheme is proposed for three-phase constant-voltage constant-frequency (CVCF) pulsewidth modulation inverters to achieve high-quality sinusoidal output voltages. In the proposed control scheme, the repetitive controller (RC) is plugged into the stable one-sampling-ahead-preview-controlled three-phase CVCF inverter system using only tw...

Discrete Sliding-Mode Control of a PWM Inverter for Sinusoidal Output Waveform Synthesis with Optima - Power Electronics, IEEE Transactions on

This paper presents a discrete sliding-mode control scheme with feedforward compensation for the closed-loop regulation of the pulse-width modulated (PWM) inverter used in an uninterruptible power supply (UPS). The proposed feedforward controller can effectively improve the tracking performance of the PWM inverter. In designing the sliding-mode controller, we have taken load disturbance into co...
