Use PID control
PID control function, (P) proportional, (I) integral, and (D) differential, play the roles to
reduce the deviation between the target command and the actual control value.
PID Control operation
Characteristics outline of the PID control is as following:
. P control : A difference (deviation) between the input command (set value) and the
actual control value (feedback). This difference or deviation will be
amplified by a set gain (P), control and reduce the system deviation.
Although the gain is increased, system might still be unstable.
. I control : This control allows that the relative gain (P) is integrated in time. Therefore,
a high gain may be used in results with small deviation. When the integral
time (I) is increased, the system response will be reduced.
