Abstract
This article is concerned with the problem of synthesizing a two-loop control system for a three-phase voltage inverter using the automatic control system with proportional-integral regulators in the internal and external loops. The paper is devoted to the improving of the inverter output voltage quality using high-frequency interference filtering in the inverter control channel. In contrast to the traditional PI controller structure, a controller with an additional filter in the inner loop is proposed. The proposed modification of the control algorithm makes it possible to reduce the influence of high-frequency disturbance by reducing the ripple component at the controller output, which generates the modulating signal for the pulse-width modulation unit, and therefore to avoid the PWM saturation mode and improve the power converter performance. The proposed method for calculating the parameters of a modified PI controller with a second-order filter is based on the time-scale separation method. The influence of several dynamic orders filters on the magnitude of high-frequency pulsations at the control system output is considered. Comparative evaluation of high-frequency disturbance suppression degree in the control channel are obtained for various structures of the proposed control algorithms. The proposed approach is demonstrated using the example of the two-circuit automatic control system synthesis for a three-phase voltage inverter in an on-board 400 Hz/115 V AC power supply system. The synthesis of control system parameters for the inverter was carried out in accordance with the requirements of the standard for general requirements and power quality standards in aircraft power supply systems. The performance of the calculated control system was tested using mathematical and simulation modeling in the Matlab/Simulink environment.
