The report presents the results of an autopilot analysis to integrate the Air Force Close Air Support Missile (CASM) laser seeker with the Army Terminal Homing Flight Test Vehicle (THFTV). This CASM/THFTV system has evolved from the Army's requirement to flight test the CASM seeker on the THFTV for evaluation of the seeker's performance, and to determine the seeker's acceptability for TRI-Service use. Utilizing root locus techniques, the CASM/THFTV system was evaluated to determine the autopilot gains and compensations required for proper system integration. Three candidate autopilot designs were derived from this study. Autopilot Design A maintains the THFTV rate loop, and only the guidance compensation is modified. Autopilot Design B maintains the original rate loop response, but the rate loop compensations are repositioned to eliminate the need for a guidance compensation. Design C is an alternate approach that simplified the compensation requirements for the rate loop and increases its response. The final determination of the best autopilot design will be derived from a simulation performance analysis of the candidates. (Author)
