本文提出了一种反馈线性化技术来控制三相不间断电源系统的输出电压控制。首先，从逆变器输出端和负载侧之间的功率平衡条件导出包括输出LC滤波器的非线性模型。然后，输入输出反馈线性化应用到非线性模型，使其线性化。利用线性控制理论设计了线性化模型的控制器。跟踪控制律的极点配置技术获得。实验结果表明，所提出的控制方案给出了高的动态响应，负载变化以及零稳态误差。
In this paper, a feedback linearization technique is proposed to control the output voltage control of three-phase uninterruptible power supply systems. First, a nonlinear model including the output LC filters is derived from the power balance condition between the inverter output terminal and the load side. Then, input-output feedback linearization is applied to the nonlinear model to make it linear. The controller of the linearized model is designed by linear control theory. The tracking control law is obtained with a pole placement technique. It is shown experimentally that the proposed control scheme gives high dynamic responses in response to load variation as well as a zero steady-state error.
