9.7 2DOF PID Control
2 degrees of freedom PID control reduces overshoot or undershoot when starting control or changing
settings.
Increasing Proportional gain 2DOF coefficient (
α
) results in quick response, and decreasing it causes
slow response.
By increasing Integral 2DOF coefficient (
β
), overshoot or undershoot can be controlled more effectively.
However, response will be slower than the usual PID control for suppressing the overshoot or
undershoot.
