Switching integral time Ti
Application use The switching I integral time is implemented in order to reduce the overshoot
in pressure control at a step response. The switching I controller can normally
be applied where the overshoot is too big and cannot be tuned through nor‐
mal method.
Working principle The parameter of I controller can be switched between two values according
to the difference between the pressure command and actual pressure:
