英文摘要：

The disturbance attenuation control of one freedom cart-pendulum system with outer stochastic excitation and uncertain disturbance is investigated. First, a stochastic nonlinear system model is proposed for the system. Then, a state feedback control is proposed to complete the Hamiltonian realization of the system. The dissipation of the system is analyzed as well. Thirdly, a disturbance attenuation controller is proposed which can effectively utilize the power generation, dissipation and transformation property of the cart-pendulum system. Simulation results demonstrate the effectiveness of the proposed method.
