Sliding Mode Observers Versus Kalman Filter in the Homing Loop
Abstract
A comparison via Monte-Carlo simulations is made of Sliding Mode Observers versus Kalman Filter in the homing missile guidance system using different guidance laws. It's shown that the sliding mode observer contributes to less miss distance due to noise than Kalman filter. Application of sliding mode estimators in the homing loop with Proportional Navigation guidance and with a phase-lead compensation based on sliding mode estimators for the flight control system phase-lag is demonstrated. It is shown that this system gives performance comparable to the optimal guidance law with Kalman filter that has perfect knowledge of all additional information it requires for estimation.
