This paper presents some techniques for driving novel 5 phase dual winding PMSM (Permanent Magnet Synchronous Motor) the in-wheel motor. The motor realizes change over characteristics that can expand area from high-torque mode to high-speed due construction. However, structure makes a high-current ripple high coupling between windings. proposes control methods reduce current ripple, including i...

The controllable electrical loss which consists of the copper loss and iron loss can be minimized by the optimal control of the armature current vector. The control algorithm of current vector minimizing the electrical loss is proposed and the optimal current vector can be decided according to the operating speed and the load conditions. The proposed control algorithm is applied to the experime...

Abstract – For precisely regulating the speed of a permanent magnet synchronous motor system with unknown load torque disturbance and disturbance inputs, an LMI-based sliding mode control scheme is proposed in this paper. After a brief review of the PMSM mathematical model, the sliding mode control law is designed in terms of linear matrix inequalities (LMIs). By adding an extended observer whi...

This paper gives new technique for estimating the rotor position for PMSM drives with higher accuracy and resolution and also controlling of PMSM motor. There are several techniques for doing same. Some of them are average and first order algorithms. Present technique which is used here is vector tracking observer in conjunction with discrete Hall sensors’ output signals, which is similar to a ...

The radial-radial flux compound-structure permanent-magnet synchronous machine (CS-PMSM), integrated by two concentrically arranged permanent-magnet electric machines, is an electromagnetic power-splitting device for hybrid electric vehicles (HEVs). As the two electric machines share a rotor as structural and magnetic common part, their magnetic paths are coupled, leading to possible mutual mag...
