Active Disturbance Rejection Control of Hydraulic Turbine based on Fully Actuated System Theory

This paper investigates the problem of stabilization control of hydroelectric generating units. Firstly, the fully actuated system model of the linear hydraulic turbine is established by using the theory of fully actuated system. Then the control law is designed by using the direct parameterization method, which can configure the closed-loop poles of the hydraulic turbine system expectation or region and ensure the stable operation of the hydraulic turbine regulating system with a small control gain. Finally, a nonlinear active disturbance rejection control method is proposed for the internal and external disturbances in the control of the fully actuated system. The simulation results demonstrate the effectiveness of the proposed control method.
