—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)
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)
