针对含有不确定参数的发电机励磁控制系统,设计了一种新型的自适应反步鲁棒励磁控制器。在设计过程中,基于反步法逐步进行控制器的设计,并引入非线性阻尼算法来减小反步法的“计算膨胀”问题,有效地增强了控制器的鲁棒性。接着介绍了应用浸入与不变自适应控制设计阻尼系数的自适应估计律。通过MATLAB软件进行仿真研究,验证了该算法的有效性和优越性。

According to the generator excitation control system with uncertain parameters, a novel adaptive backstepping robust controller was designed. In the design process, based on the backstepping method for designing the controller, the nonlinear damping algorithm to reduce the "coefficient expansion" of the backstepping method was introduced, which could effectively improve the robustness of the controller. And the adaptive estimation of damping coefficient was designed by useing the I&I adaptive control method. The simulation research was carried out by MATLAB software to verify the effectiveness and superiority of the algorithm.
