基于线性二次型调节器的三相逆变器积分+状态反馈控制
A Linear Quadratic Regulator Based Control Strategy With Integral Control and State Feedback for Three-Phase Inverter
摘要
Abstract
To improve dynamic and steady state control performances of three-phase voltage source inverters, based on internal model principle a controller adopting integral control and state feedback is designed, and the theory of linear quadratic regulator is utilized to solve the problem related to control parameters. To make linear quadratic regulator be able to be applied in the tracking, flexible transformation of controller structure is performed and the setting of controller parameters is optimized by using the method in the linear quadratic regulator theory. The effectiveness of the proposed method is validated by simulation results and experimental results of experimental prototype with capacity of 430 kW.关键词
