Abstract:
Motion tracking variable structure control theory is applied to design guidance law for passive homing missiles. This motion tracking variable structure guidance law(MTVSG) can force the missile target line of sight angular rate to vary on a given motion for enhancing observability of a passive guidance problem which is equivalent to a nonlinear system, and meanwhile guaranteeing a high hitting accuracy. Simulation studies indicate that under the MTVSG, the observability is apparently enhanced, so the estimation accuracy of the system states is relatively high. Further studies show that the MTVSG is robust to the estimation errors of the system states. The above advantages of MTVSG make the missile hit the target very accurately.
Key words: passive homing missile guidance, motion tracking variable structure control, observability
