Juhani Karhumäkiarge displacements in vibrations are seldom desirable, indeed, just the opposite holds true. The engineer makes efforts to arrange the vibrating system so that its motion is kept within the vicinity of a prescribed reference motion. When this is the case, the equations of motion relative to this ref

Carlos Martín-Vide,Gheorghe PĂunectronic computers. At present, improvements in precision are obtained by a more accurate modelling of technical systems. Thus, for instance, a system with one degree of freedom is often not accepted, as it used to be, as a model for vibration analysis in mechanical engineering. As a rule, vehicles

Kenichi Moritastorically this was the approach taken by control engineers until the introduction of state-space theory. The techniques developed in the past include Nyquist and Bode diagrams, pole assignment and root locus methods. Frequency domain methods are therefore extremely important, especially for the sup

LFP problems deal with determining the best possible allo cation of available resources to meet certain specifications. In particular, they may deal with situations where a number of resource

Didier Caucalrmance associated with a stochastic tracking system which is closely supervised by a reference command input and a desired trajectory. Both compactness from logic of state-space model description and quantitativity from probabilistic knowledge of stochastic disturbances are exploited to therefore al

Gabriel Ciobanu,Mihai Rotaruts with a brief introduction to the basics of the Cholesky decomposition technique. Subsequently, examples of applications of the technique to ab inito procedures are presented. The technique is demonstrated to be a special type of a resolution-of-identity or density-fitting scheme. This is followed
