MOTOR SPEED CONTROL WITH DROOP COMPENSATION |
摘要 |
Compensating for droop in load-speed characteristic of a DC motor, an armature current signal, which is indicative of motor load, is amplified to control armature voltage. A negative feedback reduces amplification as armature voltage increases. An operational amplifier has an input related to armature current and a negative feedback responsive to armature voltage. A transistor in the feedback path varies the feedback impedance as a function of armature voltage.
