| The elevating complexity of modern battlefield requires higher performance and better adaptability of air vehicles. As an important development trend of new generation aircrafts, morphing aircrafts are capable of doing large-scale structural change to achieve optimal aerodynamic characteristic and controllability according to different flight environments and mission requirements. Because of their complex structures and special aerodynamic(dynamic) characteristics, modelling and control of morphing aircrafts have been lasting topics of interest for researchers. Variable sweep is a classical way of aircraft morphing, however, most former researches were done based on single-rigid-body hypothesis. Meanwhile, asymmetricmorphing and the feasibility of using morphing as additional controller were rarely considered. The study on modelling and control of asymmetric variable sweep morphing aircrafts can be enlightening for other morphing aircraft researches, and its importance is quite significant. Our research is supported by the National Natural Science Foundation of China(Grant No61273090). In this paper, we propose an intensive study on multi-body dynamic modelling and flight control of asymmetric variable sweep aircrafts, and report the progress of our UAV hardware experiment platform. The major work comprises the following aspects:1. Multi-body dynamic modelling of asymmetric morphing aircrafts based on Kane’s method.2. The feasibility study of using symmetric(asymmetric) variable sweep morphing as additional attitude controller, and the following control allocating problem with traditional control surfaces.3.Integrated trajectory tracking control design of asymmetric variable sweep aircrafts with existence of external disturbances and system physical constraints.4.UAV hardware experiment platform based on Paparazzi UAV. |
