Hybrid control of five-phase permanent magnet synchronous machine using space vector modulation

Abstract

This paper aims to study the hybrid control of a five-phase permanent-magnet synchronous machine improved by the space vector modulation (SVM) technique. The torque ripples and currents will therefore be reduced. This control is based on the theory of hybrid dynamic systems (HDS), its discrete component is the voltage inverter which has a finite number of states controlling the continuous component that represents the machine. The results of the simulation made on MATLAB/Simulink are presented and discussed in order to check the performance of the strategy of the studied control. They show, in particular, the main advantages of this control manifesting the good dynamic of the electromagnetic torque and the robustness against the parametric variations.

Adaptive Cost Function FCSMPC for 6-Phase IMs

“…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].…”

“…. Cr = (36) where, components of a are linearly decreased from 2 to 0 over the course of iterations, and r1 and r2 are random vectors in [0,1]. Note that the random r1 and r2 vectors let the grey wolf select any positions in Figure 6.…”

“…Due to these merits, this has motivated researchers to increase interest in the use of multiphase machine for critical applications such as electrical propulsion systems for ships, offshore wind farms, and electric aircraft. Among the multiphase machines, fivephase and six phase induction or synchronous machines are the most considered in the literature [1][2][3][4]. In the present study a special focus will be given to the five-phase permanent magnet synchronous motor drive (PMSM).…”
