Radar homing heads of guided missiles belong to systems with astatism of the second (rarely third) order and form estimates of angles and angular velocities in one loop, which is insufficient in conditions of maneuverable air combat, since this leads to a discrepancy between the dynamic properties of the target and the inclinometer in the control algorithm. A way to eliminate this drawback is to synthesize an optimal control algorithm. The task of synthesis of optimal control consists in constructing an algorithm for controlling the drive of the antenna of the inclinometer of the radar homing head of a guided missile, which would ensure the best quality of the system, satisfying the selected criterion of control quality.
Goal of the work is development of control algorithms for the inclinometer antenna drive while tracking a maneuvering air target and assessment of their effectiveness.
Analysis of the simulation results in comparison with the existing control algorithm shows that the algorithm synthesized according to the local quality criterion has a 2.7 times less convergence time, and the algorithm synthesized according to the linear-quadratic quality criterion has 20−25% less control errors.
The results obtained make it possible to increase the efficiency of information and control systems of guided missiles up to 25%, depending on the selected control criterion.
