2-degree-of-freedom Advanced PID Control
(Enable Tracking for primary loop)
(M+P_2PIDH_T_)
M+P_2PIDH_T_
This FB optimizes the responsive performance (tracking performance) in a setting value change and control performance to a
disturbance, and outputs the result (MV). It also performs two-degree-of-freedom PID operation, PV tracking, integration
stop, derivative stop, and SV variation rate & high/low limiter processing. The primary loop can be tracked.
