Dec 30, 2016 · Gain is the ratio of output to input—a measure of the amplification of the input signal. A common example is the volume button on a stereo. This button controls the ratio of the input signal (received from the radio station) to the output signal (how loud the sound is from your speakers). In addition to feed-forward, PID controllers are often enhanced through methods such as PID gain scheduling (changing parameters in different operating conditions), fuzzy logic, or computational verb logic. Further practical application issues can arise from instrumentation connected to the controller. A high enough sampling rate, measurement ...

Generally, if you use derivative action, more controller gain and reset can be used. With a PID controller the amplitude ratio now has a dip near the center of the frequency response. Integral action gives the controller high gain at low frequencies, and derivative action causes the gain to start rising after the "dip". The proportional calculation responds to how far the measured variable is from the setpoint. The larger the error, the larger the output of the calcu-lation. The proportional calculation has a much stronger effect on the result of the PID calculation than either the integral or derivative calcu-lations. Jul 16, 2018 · Process Gain (K p) is defined as how far the measured Process Variable (PV) moves to a change in Controller Output (CO). The Process Gain is the basis for calculating the Controller Gain (KC) which is the “Proportional” tuning term associated with many of the OEM-specific forms of the PID controller.
