Figure 9 Open-Loop Phase Without Compensation
Values of P, I, and D are iteratively selected using a computer model of the open-loop transfer function that
includes the PID controller. An initial T
c
value of 30
μ
s is assumed. Phase margin, gain margin, and frequen-
cy response for several sets of terms are calculated, and working values of P = 0.16, I = 5, and D = 1E–3
are selected. Gain margin is –14.4 dB, and phase margin is improved to about 60 degrees, at the expense
of lowering open-loop frequency response to 41 Hz. At this frequency, the phase lag generated by the 2-
point velocity signal averager is 3.6 degrees. Were a 4-point averager used, phase lag would increase to
10.8 degrees at 41 Hz.
