Output feedback dissipation control of nonlinear systems and application to water-level control for a U-tube steam generator

The output feedback dissipation control problem for nonlinear systems is investigated A design approach for the output feedback dissipation controller is presented, and the robustness analysis of this controller shows that the output feedback gain is larger the L
2
gain from the disturbance input signal to the regulation output signal is smaller. The controller is then utilized to solve the water-level control problem for a U-tube steam generator (UTSG) of a nuclear power plant. Simulation results show the high performance of this new controller.
