Abstract�� In order to improve the pursuit property of flight by pilot and to relax pilot's workload, the structure and realization methods of predictive directing signal synthesis were proposed. With the realization of these methods, pilot can use gain plus time delay control characteristics and fulfill high quality tracking flight task under the display of predictive operation signal. In the predictive directing signal synthesis research for rotorcraft terrain following task, a method to eliminate the coupled effect of airspeed loop through coupled disturbance observer design was also proposed. The validity of these methods were demonstrated by simulations.
Keywords�� flight director   flight control   terrain following   generalized predictive control   coupled disturbance
