Legacy - PID Open & Closed Loop Tuning

The zip file contains two programs, TUNE_OL.eik and TUNE_CL.eik which use the Ziegler-Nichols equations to recommend PID gains based on the open and closed loop response of a system. The Readme.txt file explains their use. Very useful for tuning control systems in the field, these programs are also interesting in that they show how EIKON can be used for "traditional" programming tasks, not just HVAC controls.
