.TRANSFORM.Controls.LimPID_Hysteresis .TRANSFORM.Controls.LimPID_HysteresisBlock of a controller for set point tracking with a hysteresis element that switches the controller on and off.
If the controller is off, and the control error becomes larger than eOn, then
the controller switches to on and remains on until the control error is smaller than eOff.
When the controller is on, the set point tracking can be done using a P-, PI-, or PID-controller.
In its off-mode, the control output is zero. Thus, the parameters yMin and yMax are
used to constrain the output of the controller during its on mode only. This can be used, for
example, to modulate a device between 0.3 and 1.0, and switch it to off when the control error
is small enough.
