PID Control
Algorithm.
z
PID-A
: This is three-mode control algorithm(P(Proportional), I(Integral),D(Derivative))
and used for most control field.
z
PID-B
: Unlike the PID A equation, the controller gives only an integral response to a
setpoint change, with no effect on the output due to the gain or rate action, and
it gives full response to PV changes. Otherwise controller action is as
described for the PID A equation.
z
DUP-A
: PID-A algorithm for Heat/Cool control.
z
DUP-B
: PID-B algorithm for Heat/Cool control.
