Abstract: The control problem for a class of systems, which have characteristics of strong coupling, strong uncertainty, and strong nonlinearity as well as fast time-varying, is analyzed. Based on the dynamic characteristics, a compound control strategy is presented. The composite control method consists of three core modules, namely, strong coupling and strong uncertainty module, strong nonlinearity and fast time-varying module, and intelligent scheduling module. Taking a typical vehicle with four strong characteristics as an example, the detailed design of the composite control method is given. Finally, based on the precise simulation model, considering the inconsistencies between flight and ground test, the simulation analysis is carried out. The simulation results show that the method is effective and reliable.
