Industrial Automatic Control Systems and Controllers Annotation << Back Calculation of Complex Transfer Function Generalized Entity Mihalevich S.S. Baydali S.A. Chursin Yu.A. A method for the calculation of the transfer function of a complex object, described by a set of inertial units based on the Mason’s formula is presented. This approach allows to describe complex objects with transfer functions, which are then used to find the parameters of regulators in control systems. Also, using this method it is possible to present all system by one unit. Knowing the input of the system we can determine an output signal by passing intermediate units of the calculations, which leads to a reduction of costs for the analysis and synthesis control system. The way of calculating the algebraic loops which often arise when modeling control systems, allowing avoiding special solvers is presented. The examples of calculations the author’s software product SimSAR are showed. Keywords: algebraic loop; generalized entity; control system; Mason formula; multivariable control system.
