Abstract

In the turbine rotor bearing system, the steady control is necessary, accurate mathematical model is established to ensure the stable operation of the nonlinear control system. The traditional control method uses fuzzy PID control algorithm, because of the nonlinear coupling characteristics of control system, resulting in the fuzzy control rules is difficult to guarantee the stable solution of equation. A rotor bearing system control method is proposed based on nonlinear coupled KdV equations finite steady analysis. The transfer function of rotor delay coupling system is established, gain and phase margin tuning method of parameters is designed, two freedom degree coupled nonlinear KdV controller is constructed, finite stable solutions of the KdV equation is obtained. The control algorithm is realized. Numerical simulation results show that the control model has good control precision, and it has good stability and superior performance.
