Abstract: A control system for a d.c. motor, in which a cyclical d.c. drive signal is applied to the motor power input terminals as the system approaches balance. In each cycle, during at least part of the time interval between drive signal application to the motor terminals, a very low impedance (virtually a short circuit) is applied to the motor terminals. These braking pulses provide progressive braking as the motor approaches its balance point, limiting overshoot and ensuring a return without hunting from an overshoot condition to the balance point. As the system nears its deadband range, each braking pulse exceeds in duration the electrical time constant of the motor and constitutes a substantial portion of its associated cycle.
