摘　　要：将自抗扰Term inal滑模控制应用于水轮机调速系统,以Term inal滑模控制作为主输出,以自抗扰控制估计扰动,对扰动具有很强的适应能力,同时收敛速度快,所设计出的控制规律不包括难以准确测定的参数。针对单机无穷大系统的仿真结果表明,自抗扰Term inal滑模调速控制器可以使水轮发电机组受到扰动后迅速趋于稳定,抑制功率振荡,对于参数的变化具有极强的鲁棒性,将有效提高水轮机调速系统的性能。In this paper, auto disturbances rejection Terminal sliding mode control was used in hydro turbine governor system. In this method, the main output was made by Terminal sliding mode control and using auto disturbances rejection control to estimate disturbance. This method has a strong adaptability for disturbance and rapid convergence. The control law does not include an imprecise parameter. The simulation results of single machine infinite bus system show that the auto disturbances rejection Terminal sliding mode controller can make the system stabilized quickly after disturbance and inhibit power oscillation. The controller has strong robustness when the parameter changing. The method can improve the performance of hydro turbine control system.
