Three-phase Voltage-type PWM Rectifier Controller Design Based on Feedback Linearization

摘要

In this paper, three-phase voltage-type PWM rectifier controller design based on feedback linearization is proposed. Nonlinear systems were firstly transformed to equivalent fictitious linear multi-input and multi-output systems (MIMO) by constructing diffeomorphism matrix. Therefore, controller can be designed by classic linear control theory. Simulation results show that the proposed nonlinear controller can provide better following performance and better disturbance rejection performance than the linear controller.
