Pulse synchronizing motor control
Abstract
Abstract THERE IS DESCRIBED A MOTOR CONTROL SYSTEM IN WHICH A MASTER SOURCE OF PULSES IS COMPARED FOR REPETITION RATE AND PHASE EQUALITY WITH A PULSE TRAIN ESTABLISHING THE MOTOR SPEED. THE SYSTEM IS A DIRECT RATIO SYSTEM IN THAT THE EXACT NUMBER OF MASTER PULSES CAPABLE OF PRODUCING THE DESIRED MOTOR SPEED IS SELECTED FOR COMPARISON WITH THE PULSE TRAIN ESTABLISHING THE MOTOR SPEED. BECAUSE THE PULSE SELECTION PROCESS RESULTS IN AN UNEVEN PULSE TRAIN, A REGULARIZING CIRCUIT IS EMPLOYED TO PRESENT SUBSTANTIALLY EVENLY SPACED MASTER PULSES TO THE COMPARISON CIRCUIT. THE PULSE COMPARISON CIRCUIT IS A DIGITAL DISCRIMINATOR PRODUCING A TIME MODULATED PULSE OUTPUT FOR SUBSTANTIALLY EQUAL REPETITION RATE PULSE TRAINS AND A DIRECT VOLTAGE OUTPUT INDICATIVE OF WHICH PULSE TRAIN HAS THE HIGHER REPETITION RATE WHEN THE REPETITION RATES OF THE PULSE TRAINS DIFFER.
