Closed-Loop Control System

A closed-loop control system is a system in which the control action is somehow dependent on the output. The primary objective of a closed-loop control system is to enhance the system's stability, accuracy, and overall performance. A simple example of a closed -loop control system is a home thermostat. The thermostat can send a …

When and how to use closed loop speed control for DC motors

Though DC motors are typically driven in open loop, introducing a closed loop can increase precision in speed control for critical applications. Speed control considerations, including selection of the optimum approach and its implementation, are crucial to most motion systems.

Closed loop DC motor control

kamelryttarn January 19, 2016, 7:21pm 11. MorganS: Since the load probably doesn't change much, open loop control might be more appropriate. Just give the motor a 'kick' of, say 50% PWM, for a few milliseconds then drop back to 10-20% and ramp that up to your final speed over a few hundred milliseconds.
