摘要: 研究一种具有特殊形式的广义非线性系统的状态反馈H∞控制器设计问题·此类系统的状态方程可以分成线性部分和非线性部分·利用广义Lyapunov函数和Lyapunov方程,首先给出广义非线性系统零解渐近稳定的充分条件,然后以代数Riccati不等式的形式,得到广义非线性系统零解渐近稳定且具有H∞范数约束的条件,进而在此基础上给出静态状态反馈H∞控制器存在的充分条件,保证闭环系统具有上述性能,并利用Lyapunov方程的解提出相应控制器的构造方法,最后提供一个数值算例以证明文中结论的有效性·

Abstract: The design of static state feedback H controllers is discussed for a special class of nonlinear singular systems of which the state equation can be divided into linear part and nonlinear part. By means of the generalized Lyapunov function and Lyapunov equation, a sufficient condition that a nonlinear singular system is zero solution asymptotically stable is given. A sufficient condition is derived in terms of algebraic Riccati inequality which makes the nonlinear singular system zero solution asymptotically stable with a H norm constraint. The existence condition of a state feedback H controller is presented, guaranteeing that the resulting closed-loop system has above performance. The design method of such a controller is provided in terms of the solution to Lyapunov equation. An example is given to prove the validity of the results.
