Stabilization analysis for dissipative Hamilton control systems subject to actuator saturation and application to power systems

The finite gain stabilization of the dissipative Hamilton systems with actuator saturation is investigated. The stability and dynamic performance of the system are seriously influenced by saturation. The globally asymptotical stabilization of a closed-loop system is 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 is received, while the estimated value of gain is obtained. The results are applied to the system with excitation and steam-valving control. The example is given to illustrate the efficiency of the proposed method.
