Abstract: A method for a real-time dynamic simulation of a response of a complex system or process controlled by a plurality of driving factors Pi (i=1 . . . k), each varying in a given range of variation. The range of variation of the driving factor Pi is discretized into NPi values. A prior parametric model of simulation is obtained in the form of a functional equation connecting the response to variations in the plurality of driving factors for any combination of values of the driving factors. Their range of variation is in the form of a sum of N modes that are functions of the factors. Each mode is defined for each of the NPi discretized values. The parametric model is stored in the form of a computer program in an independent device comprising a processor capable of running the program.

Abstract: A parallel robot is composed of two kinematic chains connecting a base to a platform having two degrees of freedom so that the platform is movable with respect to the base in a plane (x, z) of a space (x, y, z) in which the directions x, y and z are orthogonal to one another. The kinematic chains each having a bend connecting a proximal sub-chain, itself connected to the base, and a distal sub-chain, itself connected to the platform. The proximal sub-chain drives the bend in translation in the plane (x, z). The distal sub-chain of at least one of the two kinematic chains includes two rods separated from each other in the direction (y). The first and second ends of each rod are connected to the bend and the platform, respectively, by respective systems of connections composed of two pivots with axes orthogonal to each other.
