“…A good predictive model and low sampling period are key factors to achieve this objective. This route has been explored in many papers dealing with identification [6,24,25], different kinds of models (including models with observers) and schemes for diminishing the application period such as in-sample or space-vector modulation [5,[26][27][28] and virtual voltage modulation [13,29].…”

In this paper, an adaptive cost function FCSMPC is derived from newly obtained results concerning the distribution of figures of merits used for the assessment of stator current model-based control of multi-phase induction machines. A parameter analysis of FCSMPC is carried out for the case of a six-phase motor. After extensive simulation and Pareto screening, a new structure has been discovered linking several figures of merit. This structure provides an simple explanation for previously reported results concerning the difficulty of cost function tuning for FCSMPC. In addition, the newly discovered link among figures of merit provides valuable insight that can be used for control design. As an application, a new cost function design scheme is derived and tested. This new method avoids the usual and cumbersome procedure of testing many different controller parameters.

“…This has favored its use as a versatile control technique for VSDs [8]. Many variants of MPC have been proposed in connection with electrical systems, and control strategies for tracking of current, torque, and speed have been successfully implemented [9]. In most cases, an enhancement over the standard approach is sought.…”

Predictive Control of Multi-Phase Motor for Constant Torque Applications

et al. 2022

Constant torque motors are needed for rotary screw compressors that are used for cooling and other applications. In such systems, the torque demanded by the load is approximately the same over the whole range of mechanical speeds. In this paper, the use of multi-phase induction machines is investigated for this type of application. The requirement of low stator current distortion is considered. A scheduled approach is used to provide the best possible tuning for each operating point, similar to the concept of gain scheduling control. Simulations and laboratory tests are used to assess the proposal and compare it with finite-state predictive control. The experiments show that a trade-off situation appears between the ripple content in stator currents in the torque-producing and harmonic planes. As a consequence, the controller tuning appears as an important step. The proposed method considers various figures of merit with cost function tuning, resulting in a scheduled scheme that provides improved results. It is shown that the approach leads to a reduction in current ripple, which is advantageous for this particular application.
