This paper presents the experimental evaluation of a commonly used methodology to tune the PI regulators of the FieldOriented Control (FOC) strategy for Permanent Magnet Synchronous Motors (PMSMs). The methodology used is based on theAbsolute Value Optimum (AVO) and Symmetric Optimum (SO) criterions. These methods employ a simplified model of the plant tobe controlled. Due to the complexity and non-linearities present in the FOC PMSM drive some divergence between the idealresponse and the real results will occur. In this paper a comparison between simulated and experimental results is carried out toevaluate the goodness of the solution obtained. The divergences observed between simulations and the results obtained in theexperimental setup are shown and it is attempted to justify the causes of them. Overall it is concluded that the method provides asatisfactory initial commissioning of the PI regulators for the drive system under study.
