Abstract: This process comprises measuring chosen particular physical parameters of a synchronous rotating machine, combining said parameters with variables defining the nominal mode of operation of the machine, obtaining from said physical parameters and said variables a set of coefficients of the first matrices (A, B, C) representing the continuous state of the machine, and obtaining from said matrices a system of continuous state equations of the machine:d /X(t)/ /dt=A.X.(t)+B.U.(t)Y(t)=C.X(t)in which:X(t) is the state vector of the systemU(t) is the input vector of the systemY(t) is the output vector of the system.

Abstract: The present invention relates to a regulator system including a model of the regulated process. This model is blocked when saturation occurs of a regulator controlled actuator in the regulated process, and the output signal of the model is then slaved to the feed-back measurement signal so as to allow the model to function again properly as soon as the saturation ends. The system applies to the regulating of industrial processes, in particular thermal processes.
