摘要
The adaptive H_∞ control problem of multi-machine power system in the case of disturbances and uncertain parameters is discussed,based on a Hamiltonian model.Considered the effect of time delay during control and transmission,a Hamilton model with control time delay is established.Lyapunov-Krasovskii function is selected,and a controller which makes the system asymptotically stable is got.The controller not only achieves the stability control for nonlinear systems with time delay,but also has the ability to suppress the external disturbances and adaptive ability to system parameter perturbation.The simulation results show the effect of the controller.
The adaptive H∞ control problem of multi-machine power system in the case of disturbances and uncertain parameters is discussed, based on a Hamiltonian model. Considered the effect of time delay during control and transmission, a Hamilton model with control time delay is established. Lyapunov-Krasovskii function is selected, and a controller which makes the system asymptotically stable is got. The controller not only achieves the stability control for nonlinear systems with time delay, but also has the ability to suppress the external disturbances and adaptive ability to system parameter perturbation. The simulation results show the effect of the controller.
