The variator in a pushbelt continuously variable transmission (CVT) enables a stepless variation of the transmission ratio within a finite range. Nowadays, the variator is electronically controlled and the variator control objectives are twofold: 1) tracking a transmission ratio reference; 2) optimizing the variator efficiency. Recently, the extremum seeking control (ESC) technique is exploited...

This paper proposes a new method for the extraction of knowledge from a trained type feed-forward neural network. The new knowledge extracted is expressed by fuzzy rules directly from a sensibility analysis between the inputs and outputs of the relationship that model the neural network. This easy method of extraction is based on the similarity of a fuzzy set with the derivative of the tangent ...

This paper presents the iterative learning control for the industrial robot manipulator that performs repeated tasks. Motivated by human learning, the basic idea of iterative learning control is to use information from previous execution of a trial in order to improve performance from trial to trial. This is an advantage, when accurate model of the systems is not available. In this paper differ...

This paper presents a feedforward control concept for lateral asymmetries in heavyplate hot rolling. A lateral off-center plate position generally entails asymmetric rolling forces, asymmetric mill stretch, and thus a wedge-shaped exit thickness that may cause a cambered plate contour and a rotatory motion of the plate. In this paper, a model of the mill stand and of the plate movement is prese...
