Abstract:

SATCON TECHNOLOGY CORPORATION PROPOSES TO DESIGN, FABRICATE, AND DEMONSTRATE A ADVANCED INDUCTION SERVOMOTOR AND CONTROL SYSTEM CONCEPT HAVING HIGH POSITIONING PRECISION COUPLED WITH OUTSTANDING ELECTRICAL NOISE CHARACTERISTICS. THE CONCEPT WILL INCORPORATE A UNIQUE MULTI-DISK, AXIAL AIR-GAP INDUCTION MOTOR DRIVEN BY A RESONANT CONVERTER OPERATING AT 20 KHZ. THE RESONANT CONVERTER USES PULSE POPULATION DENSITY MODULATION TO BOTH OPERATE THE INDUCTION MOTOR AS AN EXTREMELY POWER DENSE AND EFFICIENT, FOUR-QUADRANT, VARIABLE-SPEED ACTUATOR AND TO ACTIVELY SUPPRESS OUTPUT SHAFT TORQUE RIPPLE. THE PULSE POPULATION DENSITY MODULATION APPROACH PROVIDES INHERENT EMISUPPRESSION WHILE MINIMIZING REQUIRED FILTERING AND SHIELDING. THE PROPOSED CONTROL SYSTEM WILL BE SENSORLESS, PROVIDING FEEDBACK CONTROL BASED ON ESTIMATED MOTOR STATES. THE PROPOSED PROGRAM WILL RESULT IN A SPACE CERTIFIABLE DESIGN HAVING A COMBINATION OF SMALL SIZE, LOW EMI, AND LOW HARMONIC LEVELS NOT PREVIOUSLY POSSIBLE WITH BRUSHLESS SERVOMOTORS. PHASE I WILL PROVIDE A PRELIMINARY DESIGN AND DETAILED PLANNING FOR PHASE II. PHASE II WILL CONSTRUCT A PROTOTYPE UNIT FOR TESTING BASED ON THE PRELIMINARY DESIGN DEVELOPED IN PHASE I.
