一类不确定对象的扩张状态观测器

The "Extended State Observer" of a Class of Uncertain Systems

利用观测器形式的跟踪－微分界，对形如的不确定系统给出了“扩张状态观测器”．只要适当选取观测器中的非线性函数和相应参数，它能很好地跟踪一批不确定对象的扩张状态．

By using a t racking - differentiator with observer form, the - extended state observer' for a class of uncertain systems of the form is given in this paper. It is shown, by choosing proper nonlinear functions and related parameters of the observer, the 'extended state observer' can track satisfactorily the extended state of a class of uncertain plant.
