Lateral acceleration control method for missile and corresponding weapon systems

Claim 1

A lateral acceleration control method with commands for a missile comprising an aerodynamic automatic pilot, providing a very low response time to commands, even of great amplitude, wherein said control method comprises the association of: an aerodynamic control system having a great lateral acceleration capability, called PAF, with a force control system close to the center of gravity of said missile, and having a moderate lateral acceleration capability but a very short response time, called PIF; said association being such that its overall response to a command is given by the following equation: ##EQU5## in which: Og=the guidance command, F(p)=the PIF transfer function, G(p)=the PAF transfer function, Γex=total acceleration realized by the missile, Γ= the PIF acceleration, and Γ2=the PAF acceleration; and wherein there can be distinguished the usual response of the aerodynamic automatic pilot G(p)Og, to which there is added the PIF's response, F (1-G)Og, working on the error, (1-G(p))Og, of the PAF, in such a way that, in addition, and in the presence of a constant command and after a delay equal to the response time of the PAF, the PIF is entirely available for realizing a new action.
