A Design of Attitude Controller for Glide Range Extended Rocket Proj ectile
Abstract：In order to overcome the influence of various disturbance factors and to improve the control effect in the process of glide and flight,an optimal control method for nonlinear stochastic systems is studied. Based on the general control principle of rocket proj ectiles flight process,a differential form of attitude dy-namics model is established.Taking attack angle and yaw angle as observation variables,and rudder reflec-tion angles as control variables,the state equations,the obj ective function and the control law are deduced. The detailed expression of the adj oint function is put forward.The optimal filter is designed based on the Riccati equation.Control parameter is designed and simulation analysis is carried out with spread glide con-trol point as the feature point.The simulation results show that this controller system responds quickly and has a good control quality.
