The spreadsheet I mentioned earlier showing how EPID and CPID compare when you add integral gain (KI!=0) can be viewed at: http://www.jlab.org/~bevins/CPID_EPID/CPID_EPID.html The model used is based on Mark's example from: http://cars.uchicago.edu/software/epidRecord.html#Problems which provides an excellent explanation of why PID's should not be used as proportional-only controllers. --Brian Bevins Accelerator Controls Group Thomas Jefferson National Accelerator Facility
