The End Of The Direct Lateral Force / Composite Aerodynamic Control

This paper integrates direct lateral force control with aerodynamic control, taking the anti-aircraft missile which has the anti-guided ability in the aerosphere as research subject.The direct lateral force control includes two ways: trajectory control and position control. This research aims at lateral force control. The direct lateral force control is that more than one hundred small jet engines are installed around the missile before the barycenter. By firing up these engines produce impulse propelling force in order to adjust the position of the missile.It is the first that the compound control model of direct lateral force/ aerodynamic control has been put forward.In the case of jet engine not working, direct lateral force/ attitude compound control system becomes only aerodynamic control system. The paper designed aerodynamic control system of pith and yaw channels and roll angle stabilization system, by using unsteady-state error follow-up control theory and state observation station theory in modern control theory.In the case of jet engine working, coupling ravel of direct lateral force/ attitude compound control was realized. This paper bring forward a control scheme which can decide to start the direct lateral force scheme and fire up those jet engines each at what time. And the paper also brings forward a scheme to control the firing azimuth of rocket in the space.The last part of this paper designed a simple three-dimensional proportion homing rule according to three-dimensional opposite equation of motion of missile-target. And the simulation of the big-loop of terminal guide ,control and motion was given. The result open out the feasibility of direct lateral force/ aerodynamic control. The control style can raise the missile mobile ability in terminal trajectory.
