通过构造扩张状态观测器对受控对象内环进行动态输出反馈线性化 ,对补偿线性化后的对象外环进行预期动力学设计的方法 ,提出了基于自抗扰技术的汽轮发电机汽门和励磁综合控制策略。本控制方法解决了传统单输入单输出自抗扰控制方法在处理多输入多输出对象时协调率难以确定的问题。数字仿真表明 ,该控制方法不仅能较好地处理汽门和励磁控制的协调性 ,而且对模型的内外扰表现出了很好的适应性和鲁棒性。
By constructing an extended state observer to dynamically feedback the inner loop of the controlled object and linearizing the outer loop of the compensated linearized object, the dynamic design of the outer ring of the controlled object is proposed. The steam turbine generator door And excitation control strategy. The control method solves the problem that the coordination rate of the traditional single-input single-output ADRC control method is difficult to be determined when processing multiple-input multiple-output objects. The numerical simulation shows that this control method not only can better handle the coordination of the valve and excitation control, but also has good adaptability and robustness to the internal and external disturbance of the model.
