Nonlinear Uncertain Turbine Governor Design Based on Adaptive Backstepping Method
A novel nonlinear robust adaptive design scheme is proposed for turbine speed governor system with parametric uncertainties and unknown control gain, as well as unknown bounded exogenous disturbances. By combining the improved adaptive backstepping method with the robust disturbance attenuation technique, a systematic design procedure is developed such that the resulting closed-loop system is globally uniformly ultimately bounded, and a main steam-valve open controller for governor system is obtained consequently. In addition, the possible controller singularity problem in some of the existing adaptive control schemes can be removed, and the performance of derived controller are discussed and illustrated with the simulation on close-loop system. The theory analysis and simulation results all reveal the obtained controller owns good adaptability and robustness.
