Abstract

This study presents a PID controller design using the Direct Synthesis (DS) method for high-order systems. The DS method offers an analytical approach to parameter tuning. PID controllers are widely favored due to their simple structure and the easy with which their parameters can be tuned. Classical controller performances may not be sufficient to control unstable, integrator-containing, or high-order systems. To overcome this problem in controlling high-order systems, high-order systems can be reduced to low-order systems using model reduction techniques. PID controller designs can be realized using reduced models. In the study, two high-order systems are taken as an example, and PID controller designs are made using second-order models of these systems. In both examples, time and frequency response analyses are presented with figures, and performance evaluations are interpreted. In the control of high-order systems, very successful results are obtained with the presented method.
