三相三电平T型整流器的容错自整定控制

This article proposes a sensorless self-tuning control algorithm for a three-phase T-type rectifier. The proposed sensorless algorithm consists of three layers including an observer, which estimates grid voltages or currents based on the Kalman filter algorithm, an online estimator, which estimates the state-space matrix parameters, and a linear quadratic tracker (LQT), which is the main controlle...
