中文摘要
      单相统一电能质量调节器(single-phase unified power quality conditioner, SPUPQC)是一个强耦合的多输入多输出非线性系统. 本文在平衡流形重构系统模型, 基于逆系统方法对重构后的系统构造解耦的伪线性系统. 针对该伪线性系统采用线性二次型调节器(LQR)设计了满足一定性能指标的控制器. 该控制策略有良好的动态响应与补偿效果并有一定的实用价值. 仿真实验证明了该控制器设计的可靠性与有效性.
英文摘要
      The single phase unified power quality conditioner (SP-UPQC) is a coupled multi-input multi-output (MIMO) nonlinear system, for which it is difficult to directly design a controller based on its configuration model. In this paper, the system model is rebuilt at the neighborhood of equilibrium manifold. For the rebuilt model, the inverse system method is then employed to construct a decoupled pseudo-linear system. A linear quadratic regulator is also designed for the pseudo-linear system to meet some performances requirements. The proposed control scheme can respond fast, compensate effectively and be easily applied in practice. Finally, simulation results illustrate the effectiveness and reliability of the proposed control strategy.
