This special issue of The European Journal of Control is dedicated to some of the results of the European Community Esprit LTR Project VHS Veri cation of Hybrid Systems It consists of papers dealing with various aspects of one of the case studies treated in the project the Experimental Batch Plant at the university of Dortmund Before presenting the papers themselves it is worthwhile to say some...

Rotational smoothing is a phenomenon consisting in gain of regularity by means averaging over rotations. This present operators that regularize only certain directions, contrast to regularizing all directions. The the result rotating directions where corresponding operator performs effect. In this paper we carry out systematic study rotational for class includes k-vector-space Riesz potentials ...

Water supply systems consume large amounts of energy because of the pumping processes involved. The operational strategy of using frequency converters enables the system to work with better adjusted discharge rate to meet demand. In this case, an optimization strategy can establish an optimal procedure in order to schedule the rotational speed of pumps over a period and guarantee a volume of wa...

This paper addresses a principle of linear superposition for realizing dexterous motions of a pair of dual multiDOF robotic fingers with spherical rigid tips during manipulation of an object. Firstly, sensory feedback control algorithms to (1) realize specified contact forces between the finger-tips and object surfaces and (2) regulate a rotational angle of the object to a given set-point value...
