Abstract: Abstract We introduce a new method for torque and speed estimation of induction motors under voltage/frequency (V/f) open-loop control. In contrast to existing approaches that need the phase current, the proposed algorithm only requires the… read more here.

Abstract: ABSTRACT The paper concerns robust estimation and variable selection in heteroscedastic linear regression models. After a brief review of existing methods for estimation in such models, a robust S-estimation approach is discussed. For all methods… read more here.

DOI: 10.1080/03610926.2019.1651858
Abstract: Abstract This article is concerned with statistical inference of partially linear additive regression models where the covariates in parametric component are measured with errors. Using polynomial spline approximations, we propose bias-corrected least squares estimators for… read more here.
