摘　　要：针对UPQC中传统PI控制器对模型依赖性大,且系统参数大范围变化时,难以保证良好的动静态性能等问题,提出了一种基于CGT(command generator tracker)的直接自适应控制策略。当输入为时变信号时,该控制器能够使被控对象输出高质量的跟踪参考模型输出,从而达到渐近跟踪效果。与传统的PI控制相比,基于CGT的直接自适应控制策略具有更好的鲁棒性、灵活性和适应性。完成了相应的UPQC仿真模型及实验平台的搭建,对UPQC的补偿性能进行了仿真分析与实验。实验验证了该控制策略的有效性和可行性。To solve the problems existing in the traditional PI controller,such as the large dependence on the model and low dynamic and static performance when the system parameters change in a wide range,a direct adaptive control strategy based on CGT(Command Generator Tracker)is proposed in this study.When the input signal is time-varying,the controller can make the system output perfectly tracking reference model output,and achieve asymptotic tracking effect.Compared with the traditional PI controller,the direct adaptive control strategy based on CGT has better robustness,flexibility,and adaptability.The simulation model and experimental platform of UPQC are built to analyze the compensation performance of UPQC.The effectiveness and feasibility of the proposed control strategy are verified by experiments.
