CSMP commutation model for design study of a brushless dc motor power conditioner for a cruise missile fin control actuator. Master's thesis
Recent improvements in rare earth magnets have made it possible to construct strong, lightweight, high-horsepower DC motors. This has occasioned a reassessment of electromechanical actuators as alternatives to comparable pneumatic and hydraulic systems for use as flight-control actuators for tactical missiles. A dynamic equivalent circuit model for the analysis of a small four pole brushless DC motor fed by a transistorized power conditioner utilizing high speed switching power transistors as final elements is presented. The influence of electronic commutation on instantaneous dynamic motor performance is particularly demonstrated and good correlation between computer simulation and typical experimentally obtained performance data is achieved. The model is implemented in CSMP language and features more accurate air gap flux representation over previous work. Hall-effect sensor rotor position feedback is simulated. Both constant and variable-air-gap flux is modeled and the variable flux model treats the flux as a fundamental and one harmonic.
