摘要
为改善三相电压型逆变器动态和稳态性能,基于内模原理设计了积分控制状态反馈的控制器,并运用了线性二次型调节器理论来解决控制参数的问题。为使线性二次型调节器理论能够应用于跟踪问题,对控制结构进行了灵活变换,利用线性二次型调节器理论的方法对控制器的参数进行了最优化整定。仿真及430 kW实验样机验证了该方法的有效性。
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.
