Hydraulic Turbine Regulation based on Robust D Stability Control

This paper on the establishment of turbine regulation. Based on the nonlinear model of the system, the uncertain linear parameter model of the turbine regulation system is obtained by mathematical transformation, and the forward Euler numerical discretization is adopted. In order to comprehensively consider the robust D stability and dynamic performance, a robust D stability controller design method based on the Fibonacci method are proposed to optimize the control parameters. Aiming at the nonlinear discrete simulation model of the hydraulic turbine regulation system, the numerical calculation method of the closed-loop transition process based on inner and outer loop search is studied. The test results show that compared with the PID controller, the robust D-stable controller can make the turbine regulation system obtain more robust adaptability to nonlinear and obtain satisfactory dynamic performance.
