“…However, the EMPC method has been applied in the field of electric drive research. For instance, the EMPC technique is considered for permanent magnet synchronous motors in [23] and [24], where pre-computed control laws represented by parameterized gains are provided, or in [25], where a continuous control set MPC is considered for a synchronous motor and the quadratic programming problem is solved online using an active-set determination algorithm.…”

This work presents a novel optimization method for the implementation of finite-state modelbased predictive current controllers in electrical drives. The proposal avoids the usual exhaustive search to find the control action, reducing the computational burden. The method is based on physical considerations of the power converter voltage vectors and is easy to implement on digital signal processors. The proposal is applied to a five-phase induction machine. Experimental results are compared with those obtained by a standard model-based controller, showing the feasibility of the proposal and the improvements in terms of sampling time reduction and control accuracy.

“…Although the method is viable, it has been reported that reducing the set of available VVs reduces flexibility. In [23] the EMPC technique is considered for a permanent magnet synchronous motor. Another EMPC algorithm is presented in [24], where pre-computed control laws represented by parameterized gains are provided.…”

Multi-phase machines are increasingly used as Voltage Vector (VV). The control action is obtained miniin research and industry applications due to their inherent mizing a cost function (CF) having several objectives balanced advantages. Stator current control is a common strategy by Weighting Factors (WF). Previous works have considered face for this type of systems. The most important issue it must is regulation of currents in the torque producing plane parametric tuning of the CF [2]-[4], as well as the design and the harmonic plane. For this task, Finite Control Set of parameter-free CFs [5], [6]. However, it has been shown Model Predictive Control (FCS-MPC) constitutes an inter-that trade-offs between figures of merit are unavoidable by esting alternative to methods using modulation. However, simply adjusting the CF [7], [8]. Researchers have considered the implementation of FCS-MPC is characterized by a high reducing the sampling period to improve current tracking. This computational demand, limiting the sampling frequency.work proposes a predictive algorithm that needs less In addition, wide-band converters achieve high commutation computation time. As a result, the sampling period can frequencies, needing high sampling frequencies [9]. However, be reduced while producing predictive control. This brings FCS-MPC is intensive in computation. As a result, a limit about several benefits resulting from improved current on the sampling frequency is found for any given computing tracking. The proposed method avoids the combinatorial hardware. Fast computation of the control action has become time-consuming optimization phase of standard FCS-MPC which is the most part. The algorithm is based on physical an interesting research topic in recent years. The case of threeinsights obtained from the application of FCS-MPC to multi-phase converters is easier to study as there are no x−y currents phase drives leading to the concept of evolutionary gaps and the dynamics of the load is simpler [10]. The case of multiregions. The experimental results for a five-phase motor phase drives is more demanding. One alley of research has demonstrate improved performance. Moreover, the method been restraining the combinatorial space. For instance, in [11] tween is flexible enough to balance the trade-off appearing bethe torque producing plane and the harmonic plane. the Voltage Vector (VV) search is restricted to an area within 60 degrees of the voltage space diagram. Similarly, in [12], an angular region is pre-selected to reduce the size of control phase Index Terms-AC motor drives, Digital control, Multiset to 7 candidates for bipolar charging stations. Similarly, systems, Predictive control, Table lookup.in [13], only the outermost maximum vector are considered FCS-MPC is a direct digital control scheme where the referred to as Synthetic Voltage Vector (SVV).
