Finite control set model predictive control (FCS-MPC) methods without using a weighting factor is being investigated as the state of the art in the power electronics application. In this article, a very simple and fast technique is proposed for making the decision among the possible options. The proposed method is an amendment on the sequential predictive control. The amendment is based on understanding the importance of the torque and the flux criteria in each control interval. The criterion that results in less cross-error will be used for voltage vectors (VVs) selection. Therefore, the high sequence may switch between the torque and the flux errors in every control interval. With this method, the best option can be found without using the weighting factor. The main advantage is avoiding the selection of an option with a big cross-error (definitely nonoptimum option). While that selection is possible by the fixed sequence method. Although, simplicity and fast computation will also be achieved. The proposed method is verified by experimental tests in different operating conditions.
