This paper investigates the application of an improved dead beat digital control strategy to a 3-phase shunt active filter used for compensation of load harmonics in aircraft power systems. Due to the high rated frequency (400 Hz) such applications result particularly demanding for both power and control devices. To compensate the inherent delay of digital control systems, a simple method for predicting...
A novel hybrid control based on digital variable-band hysteresis discrete pulse modulation (DPM) control and repetitive control is proposed for a 400 Hz inverter. The good dynamic response of the DPM inverter is obtained by the digital hysteresis control, and the steady state control performance is improved significantly by the repetitive control. By utilizing the variable hysteresis band, the stability...
