Abstract :
With handling qualities requirements ADS-33 taken as design criteria, the design problem of fuzzy switching control law for a helicopter in the whole flight envelope is investigated by using the fuzzy logic theory and H∞ control approach. For every linearized model in the fuzzy state-space model of a nonlinear system, a robust controller is designed using the GA-based H∞ controller design method. The fuzzy switching control law for the UH-60A helicopter is synthesized using the proposed technique. The resulting flight control system satisfies ADS-33D level 1 requirements in the flight velocity range of interest.
