PID Tuning Tuning a control loop, or PID, is the adjustment of its control parameters (gain/proportional band, integral gain/reset, and derivative gain/rate) to the optimum values for the desired control response. Stability, or bounded oscillation, is a basic requirement, however different systems have different behavior, different applications have different requirements, and requirements may conflict with one another.

November 03, 2011Speed Control Loop A good example of a speed control loop is the action taken when adjusting the speed of the belt (or conveyor) to maintain the speed at a desired RPM (or Travel Time). This typically involves an encoder mounted on the belt/conveyor, connected to a PLC high-speed counter (HSC), used as a feedback to measure its speed.
