Good day, Can I ask about the other applications of the On/Off Control in Control System, because I am not satisfied with the results in the Internet. I hope that somebody can help me about these. Thanks for the quick reply. God Bless

ON/OFF control action - Principle

The ON/OFF control (two-position ) controller operates only when the measurement crosses the set point. In on/off control ,a valve would have only two positions fully opened or fully closed .As a result the output measurement always cycles above and below the set point. Application of On/Off control ON-OFF control is best applied to a large capacitance process that has essentially no dead time . Eg : large tank or bath A system where dead time is short and rate of rise is slow can be handled…
