| 摘 要： | 综合运用控制领域的新成果：反馈线性化方法和线性Ｈ∞控制原理，本文提出了一种鲁棒非线性控制器设计的新方法，并把这种设计方法用于电力系统鲁棒非线性励磁控制器的设计中。由于既考虑了电力系统的非线性特性又顾及了干扰的影响，所构造的励磁控制器不仅具有较好的内部稳定性而且对扰动和不确定因素有很强的适应能力。计算机仿真研究结果表明，与以往的励磁控制器相比，这种鲁棒非线性励磁控制器可以更好地提高系统的稳定性，并改善系统的动态特性。

| Abstract: | This paper deals with the problem of power system nonlinear robust control.Firstly, by synthesizing the latest achievements in the field of control theory: the feedbacklinearization method and linear Had control theory, a novel approach for the design of nonlinear robust controller is proposed. Secondly, the mathematical model of excitation controlsystem of power system is set up. And in the light of the approach above-mentioned the nonlinear robust excitation control strategy is obtained. Simulations performed on a single machine infinite bus system show that the proposed approach is validate and the designed controller is effective in enhancing the system stability, especially the large disturbance stabilityof power systems. |
