Abstract | This paper studies the decoupling control of a twin rotor MIMO system and proposes to apply robust deadbeat control technique to this nonlinear system. Firstly, the nonlinear problem is identified and system model is developed. Then we show that the system is able to be decoupled into two SISO systems, and the crossing couplings can be considered as disturbances to each other. Finally we apply a robust deadbeat control scheme to the two SISO systems and design a controller for each of them. This design is evaluated in simulations, and the final result is tested in a twin rotor MIMO system. Comparing with a traditional system with two PID controllers, this method is easy to follow, and the results show that the proposed scheme has less overshoot, shorter settling time and more robust to crossing coupling disturbances. |
