Neutral PID Control Loop Investigated in Terms of Similarity Theory

Popis výsledku v původním jazyce

A study to which extent of parameter setting the PID controller can be designed by means of dominant pole assignment for non-minimum-phase plant with delay is dealt with in the paper. Two options of the control loop are investigated, namely with and without the measurement filtering where the latter leads to a neutral time delay system which therefore has to satisfy the strong stability condition. The control loop is described in dimensionless quantities obtained by dimensional analysis. The influence of filtering on the loop dynamics is investigated particularly the effect of filter absence at all. This effect is demonstrated by the position of neutral root chain, i.e. how far from the origin lie the roots on a vertical line parallel to the imaginary axis of complex plane. To show boundaries of the dominant three pole placement possibility in the control loop the trio of poles is placed repeatedly as long as the neutral root chain crosses the imaginary axis and the boundaries are mapped in the space of similarity numbers.
