The purpose of this paper is to demonstrate experimentally the effectiveness of a model-free controller design method for multivariable systems labeled as the Fictitious Correlation-based Tuning (FCbT). It is worth noting that the FCbT tunes controller parameters directly by using a couple of the closed-loop I/O data with no need for any mathematical plant descriptions. This approach is applied to an experimental system with two inputs and two outputs, and useful results are obtained in terms of designing controllers with a fixed structure (e.g., PID controller) encountered in many industrial processes.
