Improved Robust LQR Digital Control Method for High Bandwidth Inverters With Time Delay and Uncertain Parameters

A feedforward combined with state feedback linear quadratic regulator (LQR) is proposed to reduce the output waveform distortion and load regulation of high-bandwidth inverters. However, when digital control is adopted, the additional delays introduced by each part can lead to unmodeled model errors...
