摘　　要：以非线性模型为基础,在线递推辩识为手段,提出了一种交直流并联输电系统的自适应控制方法。利用直流系统调节速度迅速的特点,结合广义最小方差自校正控制律,显著地改善了系统的动态品质。同时本方法以单输入单输出形式,使控制系统的实施非常简单。通过对一实例的自校正控制系统设计、仿真及分析,展示了自校正控制策略在交直流并联输电系统中的广阔应用前景。Based on a non-linear system model, an adaptive control methodology is presented for a parallel AC/DC power system by means of on-line recursive parameter identifications. Taking the advantage of rapid power regulatiing ability of the DC power system and combining with the generalized minimum variance self-tuning control principles, the dynamic qualities of the controlled system has been greatly improved. Using SISO form makes the control system very simple to implement. Through the design, simulation and analysis of the self-tuning control system for a practical example, it shows that the self-tuning control strategy is very promising for AC/DC power systems.
