Nonlinear Control Strategies of Three-Phase Boost-Type PWM Rectifiers

Abstract

In order to improve the properties of three-phase boost-type PWM rectifiers, scholars in different countries have began to apply nonlinear control theory to study PWM rectifiers. For this purpose, this paper introduces the nonlinear control strategies of three-phase boost-type PWM rectifiers, which includes feedback linearization, passivity control based on Euler-Lagrange( EL) model, active disturbance rejection control (ADRC) strategy. Meanwhile this paper reviews nonlinear control strategies above and points to further research.
