Description:
A digital PI servo has the following difference equation y(k) = y(k-1) + (Kp + Ki* T )* x(k) + Kp * x(k-1). This object specifies the Ki* 100000 term (integral part). Kp is 0.5. The default value of this object is 6250 that is Ki=1/16.
What is hmNetPTPPiIntegral?
This parameter tunes the integral gain (Ki) component of a digital PI servo loop used for precision timing synchronization, with higher values producing faster phase correction. Network timing specialists adjust this value to optimize the balance between responsiveness and stability in PTP (Precision Time Protocol) implementations. Fine-tuning the integral gain helps achieve sub-microsecond clock accuracy in critical infrastructure.
