Abstract in different language:	This paper deals with the model predictive control of an electric drive system. Particularly, it focuses on the use of the L1-norm to penalize a speed deviation in a cost function of the predictive control criterion. The benefits and disadvantages of such penalization are discussed considering a model of permanent magnet synchronous motor. The main goal of the paper is to achieve a feasible predictive control algorithm with the L1-norm cost. This proceeds in two stages. First, the long-horizon part of the criterion is approximated by an appropriately designed terminal cost. Second, the short-horizon part is reduced, which facilitates optimization over a continuous control domain. Validity of the approximations and considerations are demonstrated using a set of numerical examples.
