Abstract :
This paper proposed the Modified Multi-Index Control (MMIC) design method in nonlinear differential algebraic system (NDAS), according to differential geometric control theory, M derivative, etc. Firstly, principle of this method is researched. Secondly, Based on Hartman theorem, ci parameter in the method is configured in linear system. Besides, MMIC is applied to single machine infinite-bus power system, which is based on nonlinear differential-algebraic model, and excitation control scheme is proposed. Last, the simulation results demonstrate that the scheme can enhance the regulative precision of generator terminal voltage, and make states trace for their given values respectively. For the system with implicit function, dynamic and steady-state performance are coordinated effectively by the method. Thus, MMIC is valuable for application.
