Design and Simulation of Automatic Transition Control System for Helicopter Based on Model Reference Adaptive

In order to achieve the anti-submarine capabilities of helicopter, it is essential to design the automatic transition controller. According to the basic requirements of automatic transition control mode and the rational use of limiter and exponential law, the control loop of altitude and ground speed is designed. And the control between the two channels must be coordinated, so that when altitude descends to hovering altitude, ground speed close to zero simultaneously. In this paper, the method of model reference adaptive is used to correct the altitude deviation which makes altitude trajectory followed the set rules. The simulation shows that the method can make the altitude trajectory track the desired trajectory in good.
