The four-wheel-drive electric vehicle's traction chain is powered by four permanent-magnet synchronous motors (PMSM), a single three-phase, five-leg inverter (FLI). In order to achieve the behavior of mechanical differential and require parallel wheel-motors turn at identical or different speeds, using this structure, an independent control applied on each driving wheel. For particular there sh...

Based on the equation of small pure electric vehicle (PEV) and the mathematic model of permanent magnet synchronous motor (PMSM), synchronous motor (PMSM), the dynamic model is presented for small PEV driven by PMSM. With space vector pulse width modulation (SVPWM) algorithm, a velocity and current double closed-loop simulation model of PMSM control system is build in Matlab7.6/Simulink environ...

Aiming at the characteristics of permanent magnet synchronous motor (PMSM) such as strong coupling and nonlinearity, we propose a fractional-order control scheme for the speed control of PMSM system based on the analysis of the fractional calculus theory. The simulation is conducted by using Matlab / Simulink. Simulation results indicate that the fractional-order PI controller can improve the d...

This paper focuses on the performance improvements of the permanent magnet synchronous motor (PMSM) using vector control. In this paper, a neural adaptive sliding mode control algorithm is proposed to accomplish the position tracking of the field-oriented control (FOC) for PMSM. The proposed algorithm is presented by combining the fast terminal sliding mode (FTSM) with the radial but also solve...

This study presents an application of the recently reported theories of analytic signal space partitioning (ASSP) and symbolic dynamic filtering (SDF) to address degradation monitoring in permanent magnet synchronous motors (PMSM).An (experimentally validated)mathematicalmodel of generic PMSM is chosen to monitor degradation/fault events on a simulation test bed; and the estimated parameter of ...

We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of fast-varying pulsating voltages and measurements of the resulting current ripples then permit to identify the magnetic parameters by linear le...

In this paper, a novel sensorless nonlinear speed control for a permanent magnet synchronous motor (PMSM) driving an unknown load torque is developed and integrated with the vector control scheme. An extended nonlinear state observer with parameter adaptive scheme is used to estimate the states of the motor and disturbance torque avoiding the use of mechanical sensors. The parameter identified ...

Series-winding three-phase PMSMs have a higher bus voltage utilization than the conventional with star connection. This topology is suitable for applications limited voltage. However, zero-sequence current controller will reduce of series-winding PMSMs, which causes problems in flux-weakening design. The control algorithms cause to enter overmodulation region early and degrade performance suppr...

The mathematical model of PMSM, using the powerful simulation modeling capabilities of Matlab/Simulink is implemented. The entire PMSM control system is divided into several independent functional modules such as PMSM body module, inverter module and coordinate transformation module and SVPWM production module and so on. The simulation model of the PMSM control system can be obtained by combini...
