The brushless DC generator controlled by a predictive algorithm is considered in this paper. It is able to develop excellent performances such as minimum Joule losses and minimum torque ripple, at the same time. The tracking characteristic of the prime-mover is mandatory for setting the reference value of the electromagnetic torque developed by the(More)
—This paper presents the synthesis and practical implementation of a robust digital differentiator that provides the first and second derivative of a sampled smooth signal. The robust-ness of the proposed digital device, based on second-order sliding-modes (2-SMs), is analyzed with respect to measurement errors. Experimental results on an induction motor(More)
A model predictive control algorithm (MPC) suitable for Surface-Mounted Permanent Magnet Synchronous Machines (SPMs) is presented in this paper. It is based upon an accurate discrete-time model of the drive, accounting for both voltage saturation and current limitation constraints. It aims to properly manage these constraints in order to guarantee a good(More)
In this paper, a torque control algorithm for direct drive wind turbines using a twelve-phase permanent magnet synchronous electrical machine is proposed. An electrical machine oriented to output four independent 3-phase star subsystems have been introduced in order to improve direct drive wind turbine torque control, power generation and reliability. A(More)
In the present paper the electro-mechanical model of an electric vehicle suitable for battery energy management systems has been presented.

In this paper, a predictive direct torque control (DTC) of induction motor (IM) drive is presented. The control uses stator flux and current vectors as state variables. Predicted torque variation, with reference to its unforced response during each sampling time interval, is imposed with the aim of determining the pulse widths of the chain voltages of the(More)
The paper presents an original direct-drive wind turbine control algorithm for a twelve-phase permanent magnet synchronous generator. The electrical machine is characterized by four independent three-phase star subsystems with isolated neutral point. Variable speed wind turbine control is achieved through a master control algorithm which synthesizes the(More)
