2) Comfort adjustment during operation
By adjusting the PID regulator parameters at each speed segment in the elevator running process,
the comfort can be improved. The adjusting parameters are as follows.
The effective PID regulator gain
value when the given speed is lower
than the switching frequency F0
See the following
