14. Control Loops Proportional Integral Derivative (PID) loops allow for dynamic systems to be controlled Proportional Integral Derivative (PID) loops allow for dynamic systems to be controlled They take an input and compare to set- point producing an error. This error then is used to calculate the control output via the PID loops. They take an input and compare to set- point producing an error. This error then is used to calculate the control output via the PID loops.

19. PID Tuning PID automatic/manual tuning procedures should be taken from controller manual. PID automatic/manual tuning procedures should be taken from controller manual. A simple method of manual tuning is using the double half method. A simple method of manual tuning is using the double half method. Process is cycling around set point Process is cycling around set point Start by doubling P band ie 15 to 30 Start by doubling P band ie 15 to 30 Process Stabilizes but slow response Process Stabilizes but slow response Take the amount you doubled by and decrease P band by 1/2 of this. Ie +15*(1/2)=7.5 so 30-7.5=22.5 Take the amount you doubled by and decrease P band by 1/2 of this. Ie +15*(1/2)=7.5 so 30-7.5=22.5 Process is now stable but droops under set point Process is now stable but droops under set point Use the same method of double half to find the best Integral. Use the same method of double half to find the best Integral.
