Bacterial Foraging Optimization Algorithm (BFOA) has recently emerged as a very powerful technique for real parameter optimization. In order to overcome the delay in optimization and to further enhance the performance of BFO, this paper proposed a new hybrid algorithm combining the features of BFOA and Particle Swarm Optimization (PSO) for tuning a Fractional order speed controller in a Permane...

Sensorless control of Permanent-Magnet Synchronous Motors (PMSM) at low velocity remains a challenging task. A now well-established method consists in injecting a highfrequency signal and use the rotor saliency, both geometric and magnetic-saturation induced. This paper proposes a clear and original analysis based on second-order averaging of how to recover the position information from signal ...

Abstract: In this paper we are studying a problem related to the traction of an electrical vehicle (EV). The power unit is a Permanent Magnet Synchronous Motor (PMSM) piloted by the trapezoidal control, strategy. The models of the electrical vehicle, of the motor based on finite element identification and the drive, are implemented under Matlab/Simulink 7.1. The control is ensured by four close...

Abstract DSP-based on-line dead time compensation strategy of a permanent magnet synchronous motor (PMSM) drive through a signal processing and harmonic extraction for a robot arm application is proposed. The proposed scheme is based on monitoring the fifth-order harmonic component through the signal processing and harmonic component extraction. The proposed scheme does not require a periodic i...

This paper discuss about PV cell energy based space-vector pulse width modulation (SVPWM) control methods applied for an H-bridge inverter feeding a 3-phase permanent magnet synchronous machine (PMSM) in electric-vehicle (EV) applications. EVs require a high degree of availability continuity of service. Advantages using svpwm minimization of switching losses, balancing of switching rate between...

This paper presents estimation of d-axis and q-axis inductance of an interior permanent magnet synchronous motor (IPMSM) by using an extended Kalman filter (EKF). The EKF is widely used for control applications including the motor sensorless control and parameter estimation. The motor parameters can be changed by temperature and air-gap flux. In particular, the variation of the inductance affec...

In this paper, an adaptive fuzzy backstepping controller has been developed for the position tracking control of a permanent magnet synchronous motor (PMSM) drive. Fuzzy logic systems are used to approximate unknown nonlinearities appearing in the control law and an adaptive backstepping technique is employed to construct controller.
