Summary

This paper presents a practical method for tuning the parameters of a model predictive control technique for controlling the suction and discharge pressures of refrigerant compressors in test rigs. The proposed method presents a clear interpretation, based on the process dynamics and its real operation. The rig considered in this paper has two outputs, which are the pressures at the inlet and outlet of the compressor under test, and two manipulated variables, which are two valve openings. In this study, the model predictive control technique known as generalized predictive control was used and, in addition to the experimental results, an analysis of the effects of the controller tuning parameters on the closed-loop results is presented. The obtained results are promising and show that the proposed method can be used as a starting point for the tuning of predictive controllers applied to test rigs and can contribute to make parameter tuning simpler and more intuitive.
