A New Linear Parametrization for Peak Friction Coefficient Estimation in Real Time

Ricardo de Castro; Rui Esteves Araújo; Jaime Cardoso; Diamantino Freitas

The correct estimation of the friction coefficient in automotive applications is of paramount importance in the design of effective vehicle safety systems. In this article a new parametrization for estimating the peak friction coefficient, in the tire-road interface, is presented. The proposed parametrization is based on a feedforward neural network (FFNN), trained by the Extreme Learning Machine (ELM) method. ...

Electrolytic capacitors are usually used in power electronic systems for smoothing, energy storage or filtering. They have the best overall performance for these objectives being a critical element in the design of these systems, in several applications, with different requirements. But, infortunately, in most cases, they are the most life-limiting device. The expected life of electrolytic capacitors depends on...
