Webb1 nov. 2024 · Proportional band is another very important concept. The proportional band tells us the total range of the controlled output that can be produced within the controller’s 0% and 100% limits. The graph above shows the same straight-line equation of proportional output or term ( P o u t) versus error. Webb30 juli 2024 · Proportional control We start by setting K i and K d to zero, and by disabling the low-pass filter. We'll only vary the proportional gain factor K p . This means that the control signal we send to the motor is proportional to the distance between the actual fader position and the desired fader position.
