finding PID coefficient for my PLL system question

Hello,I have a feedback loop as shown below,We are fixing the noisy YIG with a cavity resonator and feedback.(shown in the attached paper and diagram below).
the phase difference between the signal is transformed into voltage that feeds the yig and changes the frequency of the YIG proportionaly with the voltage we enter.
generally speaking if i use a amplifier as shown bellow then from control theory i get P controller.
1.What if i want to create a PID controller for the error fixing,will it work better?
could you please reccomend me tip on how to make a good PID that will .
from the diagram beloow i have thee do i know how to plan the PID properly for my system it has coefficients.
how do i deside what K_P K_I and K_D to create?
