Paper Abstract

The effectiveness of a HWIL facility for developing missile guidance and targeting systems is limited by the quality of the elements that simulate the continuous physical processes. A motion simulator, which stimulates the inertial measurement and targeting sensors, must produce motion that is consistent with the actual physical processes. The effectiveness of a HWIL simulation is progressively degraded by each non-ideal element or process in the loop. The interface between the simulation computer and the motion system is traditionally a problematic link that is resolved once and for all in the Acutrol3000 Motion Control instrumentation. This paper focuses on issues relating to data synchronization, time skew correction, multi-rate data smoothing, and reduced state motion vectors. Concepts are addressed and results are presented.
