Nonlinear Adaptive Robust Governor Control for Turbine generator

This paper presents a design approach to nonlinear adaptive control of turbine speed governor systems with parametric uncertainties and exogenous disturbances. It is shown that the stabilizing control law with desired L₂ gain from the disturbance to regulated output can be designed by the dynamic surface control method in a recursive way without linearization. Based on this method, both the design procedure and the derived tracking controller itself are simplified, and he derived controller guarantees that the output of resultant closed-loop system converges to the stable-state operation point with the L₂ performance. Besides, the dynamics of the system can be adjusted via an appropriate choice of design parameters of the controller. Simulation results demonstrate that the proposed controllers guarantee dynamic stability of the system regardless of the system uncertainties and disturbances.
