Modeling and Simulation of Controllers of Aircraft Power Supply System Based on Finite State Machine

In order to validate the control and protection logic of aircraft power supply system, the model of the controllers of aircraft power supply system was built. Contrasting with different methods in modeling controllers, a kind of method using Finite State Machine(FSM) in the scheme design phase was pointed out. This method was proved by modeling the aircraft generator control unit as an example. The results show that the model meets the design requirements and its control logic is correct and the temporal logic is exact. The method of modeling is easy and fast.
