1 OVERVIEW

(5) PID algorithm using a velocity type incomplete differential format

Partial differential has the following advantages over the complete differential format.

(a) The differential gain is 1/

and the limit value can be set.

(b) The output contains time amplitude, so the system actually responds to the operation edge

so the derivative operation makes the movement valid.
