I've got a control loop controlling the speed of a pump with a VFD as a function of a flow meter measured GPM. When the GPM is increasing, I want the response of the pump speed to gradually speed up (PI loop with big I). When the GPM is decreasing, I want the pump to immediately slow down (PI loop with little I).
