一类非线性不确定相似组合系统的鲁棒镇定

Robust Stabilization of a Class of Nonlinear Uncertain Composite Systems with Similar Structure

利用相对度给出了对非线性组合大系统相似结构的刻划，讨论了这种具有相似结构的非线性组合系统的鲁棒镇定问题·采用输入输出线性化与变结构控制相结合的方法设计出鲁棒控制器以确保系统在其平点处是渐进稳定的·结果表明系统的相似结构简化了对系统的分析与设计·

The description of similar structure of nonlinear composite systems was put forward and the robust stabilization of such systems with similar structure was discussed. With the input output linearizing method and sliding mode control, the robust controllers proposed to guarantee the controlled systems is asymptotically stable. The similar structure of composite systems can simplify the analysis and design of systems.
