摘　　要：设计了多机电力系统发电机励磁的自适应鲁棒Terminal滑模控制器,将L2增益干扰抑制、自适应逆推法、Terminal滑模控制相结合,可以自适应估计发电机的不确定阻尼系数,对扰动具有鲁棒性。给出了控制器的设计过程。针对2区域4机系统的仿真结果表明,所设计的自适应鲁棒Terminal滑模励磁控制器能够快速抑制功率振荡,有效提高电力系统的暂态稳定性,并保持机端电压的恒定。The adaptive and robust generator excitation controller with terminal sliding mode for multi-machine power system is designed.L2-gain disturbance attenuation,adaptive backstepping method and terminal sliding mode control are combined to adaptively estimate the uncertain damping coefficient of generator and possess robustness to disturbance.Its design steps are given.Simulative results for 2-area 4-machine power system show that the designed controller restrains the power oscillation quickly,improves the system stability effectively and maintains the terminal voltage constant.
