ON PID CONTROLLER DESIGN FOR A HIGH-ORDER SYSTEMS

Abstract

Investigation of PID (proportional-integral-derivative) controller and its shorter variants (PI and P) for high-order systems has been carried out and presented in this paper. Famous Ziegler-Nichols method based on frequency response was used without previous model reduction of system. Tuning procedure and system functioning were performed by means simulations. According specificity in the obtained results, caused by system particularities, some corrections in the PID parameters tuning rules have been suggested. Applicability of proposed procedure has been proved on the several high-order systems.
