Abstract
AN INNOVATIVE APPROACH TO DESIGNING AN ADAPTIVE BBT MISSILE AUTOPILOT USING A TECHNIQUE KNOWN AS GSLQ IS THE BASIS OF THE FOLLOWING PROPOSAL, THE BENEFITS OF WHICH INCLUDE: (1) BEST TRADEOFFSBETWEEN PERFORMANCE AND ROBUSTNESS AMONG DIFFERENT DESIGN METHODOLOGIES; (2) THE ABILITY TO ACHIEVE LOOP TRANSFER FUNCTION RECOVERY (LTR) EXACTLY, AND NOT ASYMPTOTICALLY; (3) ADDITIONAL POLE PLACEMENT CAPABILITY AND REDUCED-ORDER CONTROLLER CAPABILITY; (4) ELIMINATION OF THE HIGH GAINS AND, THEREFORE, HIGH CONTROL ACTIVITY TYPICALLY FOUND IN LQG/LTR; AND (5) THE GAIN MATRIX BECOMES AN EXPLICIT FUNCTION OF SYSTEM PARAMETERS AND CONTROL BANDWIDTH, MAKING IT POSSIBLE TO IMPLEMENT A STRAIGHTFORWARD GAIN SCHEDULE OR AN ADAPTIVE CONTROL SCHEME FOR THE ENTIRE FLIGHT ENVELOPE WITH OPTIMAL PERFORMANCE. PHASE I IS FOCUSED ON: (1) DESIGNING A HIGH PERFORMANCE MIMO ADAPTIVE AUTOPILOT CONTROL LAW FOR A SPECIFIC AIR-TO-AIR MISSILE; AND (2) PERFORMING ANALYSIS AND EVALUATION OF THE RESULTING CLOSED-LOOP CONTROL SYSTEMS OVER THE ENTIRE FLIGHT ENVELOPE, ENSURING HIGH PERFORMANCE AND GOOD ROBUSTNESS. IN THE PHASE II, THE EFFECTIVENESS SHALL BE DEMONSTRATED VIA IMPLEMENTATION OF BOTH SOFTWARE AND HARDWARE IN A REAL-TIME ENVIRONMENT. FURTHERMORE, A USEFUL, UNIFIED PROCEDURE FOR DESIGNING A ROBUST, INTEGRATED CONTROL LAW FOR ADVANCED BBT MISSILE SHALL BE DEVELOPED. THIS INCLUDES: (1) A SIMPLIFIED DIGITAL CONTROLLER DESIGN PROCEDURE; AND (2) A CAPABILITY TO RESOLVE ALL PRACTIAL IMPLEMENTATION ISSUES.
