The intelligent optimal design problem of integrating control law and distributive law for multi-dimensional heterogeneous composite attitude control system is studied with taking aerorudder/thrust vectoring/direct force composite control aircraft as the object.Firstly,a multi-dimensional heterogeneous intelligent composite control algorithm framework of"intelligent control law+intelligent distributive law"for aircraft attitude based on PSO algorithm is proposed.And the control system model is established.Then the implementation method of intelligent optimization algorithm for control laws and distributive law parameters is mainly studied.Finally,the effectiveness of the proposed method is verified through mathematical simulation.The simulation results show that the proposed intelligent optimization composite control system can both achieve accurate and fast tracking of attitude angle commands in case of the nominal model or perturbed model.
