中文摘要: 利用绝对稳定性方法分析自抗扰控制器,给出了其控制线性对象的稳定性的充分条件,详细讨论了一阶自抗扰控制器稳定的充分必要条件,最后针对一类可作第一近似展开的非线性控制对象,证明其稳定性取决于其第一近似线性对象.
Abstract:The close-loop stability of ADRC is analyzed by using absolute stability theory. In order to use the absolute stability theory，ADRC is simplified to meet Lurie system. One-order ADRC is analyzed in detail and necessary or sufficient conditions for absolute stability are obtained. If a nonlinear control object can have first approximate linear sysrem，it is proved that the close-loop system of the nonlinear object and ADRC is in gradual stability if the close-loop system of the first approximate linear sysrem and ADRC is in absolute stability.
