Stabilization and L₂ Disturbance Control Based on Generalized Hamiltonian Model of Hydro Turbine Generating Sets

Abstract:

The hydro turbine generating sets model exists uncertainty in structure and parameters due to its complex structure and operating states multiformity. Especially, the adaptability and robustness of controller is more important for the stabilization control at equilibrium point under given output. Based on Hamiltonian control model of nonlinear hydro turbine generating sets, the L2 disturbance attenuation control is added into the stabilization control to restrain disturbance from model and structure parameters in this paper. The L2 additional control is proved to be asymptotic stability, and its control low is derived. Simulation results show that adding L2 additional control, system can stable to given equilibrium point and has more adaptability and robustness.
