【Abstract】 Based on the multivariable nonlinear control systems theory, the pseudo-linearization method was applied to design the control law for the controlled system with nonlinear and non-minimum-phase characteristics and to realize the state feedback linearization of the controlled system. To satisfy the specific requirements, the pseudo-linearization method can be combined with other control technologies to design a hybrid control strategy. The digital simulation results of the hydraulic turbine regulation system indicate that the hybrid control strategy can improve the dynamic performance and strengthen the adaptive ability to real-time parameters with fast response and strong robustness.更多还原
