摘　　要：针对单机无穷大系统,结合积分逆推法和Terminal滑模控制,设计了一种静止无功补偿器与汽轮机汽门的协调控制器。按照逆推设计方法,逐步构造李雅普诺夫函数,在构造虚拟控制器时引入误差的积分项,消除余差,给出阻尼系数的自适应律,并在最后一步加入Terminal滑模面,从而得到最终的控制规律,对干扰进行抑制,使相关变量能够在有限时间内收敛到零。仿真结果表明,所设计的协调控制器提高了系统的暂态响应性能。According to the integral backstepping method and terminal sliding mode theory, a coordinated control of SVC and steam turbine-generator for single-machine infinite bus power system is designed. In accordance with the backsteping approach, the Lyapunov functions are constructed step by step, and virtual error integral is introduced into Lyapunov function to eliminate the residual error. The adaptive law of damping coefficient is given, then the terminal slide surface is added, the whole control law is obtained by applying the sliding mode control theory and disturbance is attenuated to make correlated variables converge to zero in finite time. Simulation results show that proposed coordinated control can improve the transient stability.
