Imprecise speed control can also lead to problems with chassis resonance, audible harmonics or performance during airflow blockage. Very precise management of speed can be achieved with a method known ...

Industrial control systems can be categorized in two types: open-loop and closed-loop systems. The open-loop control system is a continuous control system that provides no feedback from its output.

System Closed-Loop Control. Once you've added smarts to the basic TRIAC control topology, ... Fig. 5 is a simple block diagram of the desired system.

With closed-loop control, poor performance typically manifests itself as deviations from set point. By analyzing these deviations, one can determine if they are caused by suboptimal controller tuning ...
