This paper presents a nonlinear backstepping controller derived for control of a gas turbine. Specifically, it enables a gas turbine to provide mechanical power equal to the load, while controlling the frequency to a desired value. The resulting controller is then compared to a standard droop controller, where the new control solution shows improved performance in terms of smaller overshoot during...
A simple procedure to include state inequality constraints in the unscented Kalman filter is proposed. With this procedure, the information of active state constraints influences the state covariance matrix, resulting in better estimates. In a numerical example, the approach outperforms the extended Kalman filter implemented with constraint handling via ldquoclippingrdquo.
The principle of state estimation of a dynamic system using Unscented Kalman Filter (UKF) and Extended Kalman Filter (EKF) is briefly described. Two nonlinear examples are considered to compare the state estimation using UKF and EKF. A Solid Oxide Fuel Cell (SOFC) combined with Gas Turbine (GT) hybrid system is described and system level modeling of the hybrid system is discussed. The state estimation...
In this paper we have developed low complexity, control-relevant models of all the components of the SOFC-GT hybrid system which is connected to a load through a bus bar. A control structure is designed by analyzing the complete system and simulation results are presented
