Abstract:

This paper reviews the competition of the adaptive technique with other techniques. The inherent drawback of the adaptive technique in application to aircraft systems is considered in the light of the analysis of the features of flight control systems. The potentials and perspectives of the adaptive technique are also suggested.The development of advanced aircraft demands enhanced performances which go beyond the capacity of airdata scheduling technique. Therefore, the adaptive control schemes are expected to be applied to these flight control problems. In order to make full use of the advantages, such as saving sensor hardware, requiring less priori knowledge of aircraft: and providing higher flexibility, it is necessary to carry out robustness research of existing adaptive control schemes and to develop new more robust adaptive control schemes.
