Guidance law implementation with performance recovery using an extended high-gain observer

Authors:  Kemao Ma, Hassan K. Khalil, Yu Yao

Abstract:
Guidance law of a homing missile is implemented using an extended high gain observer without the model assumptions on target maneuvers. First, for a class of multi-input–multi-output nonlinear systems, extended high-gain observers are used for output feedback control with partial practical stabilization. Then the method is applied to the guidance law implementation of a homing missile with bearing only measurement. Simulation results show satisfactory performance.
