中文摘要：
研究了具有执行器饱和耗散Hamilton控制系统的有限增益镇定问题。饱和现象大大影响控制系统的稳定性和动态性能,严重影响系统的工作性能,利用饱和静态输出反馈使系统达到全局渐近稳定。对系统中的非线性函数做进一步演变,实现闭环系统的有限L2增益输入输出镇定,并获得增益估计值。把结果应用在励磁—汽门开度饱和的单机无穷大电力系统中,例子的分析与仿真验证了方法的有效性。
英文摘要：
The finite gain stabilization of the dissipative Hamilton systems with actuator saturation was investigated. The stability and dynamic performance of the system were seriously influenced by saturation. The globally asymptotical stabilization of a closed-loop system was received with the static output feedback. Then,under the evolution of nonlinear functions of the system,the L2 gain stabilization of the closed-loop system was received,while the estimated value of gain was obtained. The results were applied to the system with excitation and steam-valving control. The example was given to illustrate the efficiency of the proposed method.
