Absolute Stability of General Lurie Type of Discrete Control Systems

目的研究一般Ｌｕｒｉｅ型离散控制系统的绝对稳定性．方法应用Ｌｙａｐｕｎｏｖ函数方法，并引入了关于变元σ绝对稳定的概念．结果得到了上述系统绝对稳定的充要条件及一些简洁的充分条件，并给出了两个简单的例子以说明结果的有效性．结论本文推广了前人的相应结果，并得出了更一般的结果．

Aim To study the absolute stability of general Lurie type discrete control system. Methods\ Lyapunov function methods was used and the concept of absolute stability about the variable σ was introduced.Results\ The necessary and sufficient conditions and some concise sufficient conditions of absolute stability were obtained for the above systems. Two simple examples illustrated the validity of the results.Conclusion\ The previous results were improved, and some more general results were obtained.
