Abstract
Finite-set model predictive torque control (PTC) has been proposed as an attractive control strategy for drives, presenting high dynamic performance and a simple implementation. Its simplicity is due to the evaluation of single cost function based on the mathematical model prediction, however, the cost function needs a weighting factor to normalize and/or increase the importance of one of them control objectives, in this case torque and flux. Nowadays these weighting factors are a problem because there is no analytical method to determine its value, only there are some recommendations or suggestions for some specific applications. This paper validates the sequential model predictive torque control (SMPTC), which is a new strategy that does not need weighting factors, in a permanent magnet synchronous machine (PMSM) drives and compares its performance with the PTC standard. Simulation results are presented to demonstrate the good performance of SMPTC for PMSM and make the comparison with the PTC standard.
