Sliding mode control strategy of the three phase reactive power compensator
A new control strategy of instantaneous reactive power compensation is presented in this paper. The approach is based on the PWM switching technique in the rotating d-q reference coordinate frame for a three phase AC-DC power converter and on the introduction of sliding mode motion into the control system. This study is valid for steady and transient states in three phase systems. The principle control strategy, the PWM switching pattern, and simulation results are presented.<<ETX>>
