Open-Loop vs. Closed-Loop So where exactly does open-loop end and closed-loop begin? The line seems clear for some systems, but muddy for others. How much feedback is enough to qualify?

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.

For those in the transit industry, it’s easy to get lost in the jargon. Terms like card-based, account-based, open-loop and ...

Isn’t it time colleges adopted an open loop system instead of serving as conventional end-points? This would re-energise one’s potential ...

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, ...

The first randomized phase 2 trial to evaluate outcomes for spinal cord stimulation finds an advantage for an investigational closed-loop system over open-loop.
