SIMPLE CONTROLLER TUNING AND NON-OSCILLATORY PLANT IDENTIFICATION

This article is devoted to the simple PI and PID analog and digital controller tuning for non-oscillatory proportional plants of the first and second order with time delay. The approach is a modification of the desired model method and it uses for fine-tune up the only one varying parameter – the controller gain. New identification method is described as well. It enables the acquisition of plant transfer functions in a form suitable for mentioned tuning. All resultant formulas are brought out in easily memorizable forms. The use is shown in the example.
