One segment of a process control system. An open-loop control process requires human intervention, whereas a closed-loop system is entirely automated (see PID). See process control.

In control strategies, an open-loop control system refers to a controller whose action is determined based on predetermined input values without considering feedback.

The weakness of the open-loop system is clear: without any feedback, the system cannot automatically adjust its process to change its output. This rigidity, the inflexibility of an open-loop system, ...

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.

In motion control applications, you frequently hear all sorts of loops -- open, closed, current, torque, speed, voltage, and so on. Here, we define and explain these terms.

The open-loop heating system has some advantages, including design simplicity and ease of maintenance. With only voltage applied to a heat source, this method does not require an elaborate control ...

The design concepts of control theory like open loop and closed loop controller give another vision and maybe a clearer and more general view on the functionality and inner working of many software ...

Of course, a “simple” open-loop control system can mean a steeper learning curve. It’s not easy to learn to drive a manual transmission.

Today on Hackaday Dictionary, we’re going to talk about the two basic types of control systems: open-loop and closed-loop. We’ll describe the differences between them and explore the various ...
