Abstract
THE FOLLOWING PROPOSAL COMBINES TWO TECHNICAL INNOVATIONS, A GENERALIZED SINGULAR LINEAR QUADRATIC (GSLQ) ADAPTIVE CONTROL SCHEME AND A CEREBELLAR MODEL ARITHMETIC COMPUTER (CMAC), FOR THE PURPOSE OF ACHIEVING A HIGH PRECISION, ROBUST, ADAPTIVE WEAPON CONTROL SYSTEM DESIGN. THE BENEFITS OF THE RESULTING WEAPON CONTROL SYSTEM ARE SEVERAL: (1) A MULTI-INPUT AND MULTI-OUTPUT (MIMO), ADAPTIVE CONTROL LAW DESIGN; (2) AN ADAPTIVE, MAXIMUM HIGH CONTROL BANDWIDTH WHICH IS A FUNCTION OF THE MAGNITUDE OF THE DISTURBANCE INPUTS AND COMMANDS; (3) THE ELIMINATION OF DETAILED, ACCURATE KNOWLEDGE OF SYSTEM DYNAMIC PARAMETERS SUCH AS MECHANICAL FRICTION AND STRUCTURE RESONANT FREQUENCY, SINCE THE RESULTING CONTROL LAW IS PRINCIPALLY A FUNCTION OF CONTROL ACTION EFFECTIVENESS, WHICH CAN BE DIRECTLY MEASURED ON-LINE; (4) ROBUSTNESS TO A WIDE RANGE OF SYSTEM DYNAMIC PARAMETERS SUCH AS MECHANICAL FRICTION AND STRUCTURE RESONANT DYNAMICS; AND (5) INCREASED TARGET TRACKING ACCURACY FOR FIRE-ON-THE-MOVE APPLICATIONS. PHASE I FOCUSES ON: (1) DESIGNING A HIGH ACCURACY MIMO ADAPTIVE TURRET WEAPON CONTROL LAW FOR A SPECIFIC WEAPON TURRET CONFIGURATION; AND (2) PERFORMING ANALYSIS AND EVALUATIONS OF THE RESULTING CLOSED-LOOP CONTROL SYSTEMS OVER A WIDELY VARYING VIBRATIONAL ENVIRONMENT, ENSURING HIGH ACCURACY AND GOOD ROBUSTNESS. IN PHASE II, THE EFFECTIVENESS SHALL BE DEMONSTRATED VIA IMPLEMENTATION OF BOTH SOFTWARE AND HARDWARE IN A REAL-TIME ENVIRONMENT. FURTHERMORE, A STANDARDIZED MIMO ADAPTIVE CONTROL IMPLEMENTATION MODULE FOR ADVANCED PRECISION WEAPONS SYSTEMS SHALL BE DEVELOPED. THIS INCLUDES: (1) A SIMPLIFIED ADAPTIVE DIGITAL SERVO CONTROLLER IMPLEMENTATION SCHEME; AND (2) ALL NECESSARY SOFTWARE AND HARDWARE REQUIRED FOR IMPLEMENTATION.
