Abstract


Precision-guided missiles are widely used in modern high-tech warfare. Thereason is that the precision-guided can weaken the enemy’s main force with theminimum cost. We need proper guidance law in order to achieve precision-guided.In addition to the greatest degree of damage target, we should constrained missileterminal ballistic inclination. So many scholars study guidance law with terminalangular constraint. Traditional guidance law based on the Lyapunov stability theorycan only make sight angular velocity tends to zero when the time is infinite. Whilethe finite time convergence control method can make controlled amount trend tozero in finite time. So using the finite time convergence control method can makethe missiles more accurate and rapid. So in the guidance process, the seekers is veryimportant The sight angle tracking is a major part of the work seeker. So we needadd seeker process to the guidance process in order to get a more precise guidancelaw. In addition, we need to optimize the seeker’s and guidance law’s parameters.Firstly, the integrated guided missile control model was established in thispaper, according to the equation of missile motion, target motion, relative motionand some solver equation.Then, the finite time convergence control theory was combined to deduce thefinite time convergence control law with angular constraint.Then, the working principle of the seeker angle tracking was analyzed. Themodel of the seeker angle tracking part was established.Then, the affection in the guide process created by the parameters of the seeksand integrated guidance and control law was analyzed. The main affectionparameters of the amount of off-target and terminal ballistics was selected They arethe parameters needed to be optimized.Finally, the genetic algorithm was used to optimized the parameters of theseekers and integrated guidance and control law. The simulation analysis of thevarious aspects mentioned by preamble was made. The simulation results the seekermodel and integrated finite time convergence guidance control law can satisfy theperformance requirements. Besides, the designed optimization method of seekermodel and integrated guidance and control law has a good optimization results. Themethod can greatly improve the performance of the seekers model and guidance law.
