PID control
(2) PID action overview
1) PI action
2) PD action
3) PID action
A combination of P action (P) and I action (I) for providing a manipulated
variable in response to deviation and changes with time.
[Operation example for stepped changes of measured value]
(Note) PI action is the sum of P and I actions.
A combination of P action (P) and differential control action (D) for
providing a manipulated variable in response to deviation speed to improve
the transient characteristic.
[Operation example for proportional changes of measured value]
(Note) PD action is the sum of P and D actions.
The PI action and PD action are combined to utilize the advantages of both
actions for control.
(Note) PID action is the sum of P, I and D actions.
