LQR with Integral Action for Phase Current Control of Constant Switching Frequency Vienna Rectifier

Abstract

This paper deals with the design of a linear quadratic regulator (LQR) with integral action (LQIR) to improve dynamic performance of a three-phase Vienna rectifier. The integral action is added to cancel the steady state errors knowing that the standard LQR controller provides only proportional gains. The controller is designed to achieve overall output… (More)
