摘要： 针对含有参数不确定性及外部扰动的静止同步补偿器(static synchronous compensator,STATCOM)单机无穷大系统,研究了鲁棒H∞控制问题.应用改进自适应backstepping方法及Lyapunov方法构造出系统的存贮函数,同时设计出鲁棒H∞控制器及参数替换律.在内部扰动中重点考虑了阻尼系数不易精确测量的影响,该控制器不仅保留系统的非线性特性和对未知参数的实时在线估计,而且能够有效抑制干扰对系统输出的影响.仿真结果表明所提控制器的有效性和优越性.

Abstract: For a single machine-infinite bus system with static synchronous compensator (STATCOM) of which the parameter uncertainty is involved under external disturbance, the problem of robust H∞ control is studied. Storage functions of control system are constructed on the basis of modified adaptive backstepping and Lyapunov methods, with a robust H∞ controller and the parameter substituting law designed simultaneously. With the fact that the damping coefficients are hard to measure accurately in the internal disturbance emphatically considered, the proposed controller is able to not only keep the nonlinearity of power system and the real-time parameter estimation but also constrain the influences of disturbance on system output. The simulation results verified the effectiveness and advantages of the proposed controller.
