Hello, There are processes that process reaction curve is slightly different from what you illustrated.Level is integrating in nature.Step change as an input leads to a ramp as process reaction. This article from Professor "Bernd-Markus Pfeiffer" in "International Journal of Adaptive Control and Signal Processing-2000" describes a universal tuning algorithm for almost all practical processes.This algorithm is utilized to implement PID Self tuner from SIEMENS. Towards ‘plug and control’: self-tuning temperature controller for PLCBest regards, Hamid Hosseini |
