With the appropriate transformation to the system model, this paper proposed the nonlinear control strategy for differential algebraic system based on the linear control law. Applying the method to single machine infinite-bus power system, which belongs to a nonlinear differential algebraic model, a nonlinear excitation control law has been designed. Simulation results show that the control law can enhance the stability of the system, also it can improve the regulative precision of generator terminal voltage, make each state trace for their given values rapidly. It manifests that the proposed method can effectively solve the design problem for nonlinear differential algebraic system and it is valuable for application.
