Having a current negative feedback speed control system

  
Another solution would be to improve the current feedback signal to an error amplifier summing junction incorporated into, a current feedback loop to increase. Figure this scen

ario. L292 circuit, and electrical current is proportional to the average current in the external circuit of motivation 5 feet and 7 feet between the flows As shown above, sampling through an operational amplifier adjustment from 510fl resistance after delivery to the error amplifier 2 feet. Feedback coefficient by the potentiometer RP, tuning. Appropriately adjusted RP, suppressed the influence of load current on speed.
