Ali, Riyadh G. Omar Electrical Engineering Department, College of Engineering, Mustansiriyah University, Iraq Article Info ABSTRACT Article history: Received Oct 16, 2020 Revised Jan 16, 2021 Accepted Jan 29, 2021 In this, work the finite control set (FCS) model predictive direct current control strategy with constraints, is applied to drive three-phase induction motor (IM) using the well-known field-oriented control. As a modern algorithm approach of control, this kind of algorithm decides the suitable switching combination that brings the error between the desired command currents and the predicated currents, as low as possible, according to the process of optimization. The suggested algorithm simulates the constraints of maximum allowable current and the accepted deviation, between the desired command and actual currents. The new constraints produce an improvement in system performance, with the predefined error threshold. This can be applied by avoiding the switching combination that exceeds the limited values. The additional constraints are more suitable for loads that require minimum distortion in harmonic and offer protection from maximum allowable currents. This approach is valuable especially in electrical vehicle (EV) applications since its result offers more reliable system performance with low total harmonics distortion (THD), low motor torque ripple, and better speed tracking.

INTRODUCTION Most of the electric vehicles (EV) developed so far are considering dc machines, permanent magnet synchronous machines (PMSM), or induction machines. The suitability of dc machines motivates the EV designers to investigate different types of ac machines. The rated power limitation of the PMSM, along with the significant expense of permanent magnets, make these machines less applicable for EV applications. These motors require a larger size and higher weight when designed for high speed. The maintenance of minimal effort of IMs attracts many EV designers to consider them as an alternative to the machines above. Recently, predictive control made huge attention to plan new power electronics drive systems. The rule of activity of this kind of control relies upon the load model, by predicting the following activity of the factors to be controlled, the controller then employs this prediction with predefined improvement procedure, to decide ideal control directions [1, 2]. The predictive control approach has many advantages that make it more usable in controlling converters, such advantages are the basic standard of activity, simple to carry out, furthermore, it can be achieved in different kinds of voltage source converters. On the other hand, it requires a notable number of computations; nevertheless, using fast PCs can take care of this issue [3-6].
