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. But if you don’t know how to drive one, ...

If, after the final step, the PV does not return to the same value as after the first step, deadband exists in the control valve (figure 5). Also realize that every control loop has a limit on its ...

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 ...

According to Festo, piezoelectric valves consume 95% less energy than solenoid valves. Piezoelectric valves open proportionally for precision control of pressure and flow and are reportedly fast ...

Oriental Motors is exhibiting its Alphastep Hybrid family of positioning products as well as its high torque stepper motors at PACK EXPO Las Vegas. The company’s Alphastep Hybrid Control System uses a ...

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. THIS ...
