MODELS OF CONTROL SYSTEMS WITH PARAMETRIC AND ADDITIVE-PARAMETRIC FEEDBACK

For processes implemented in object management systems of various nature, quite often the input signal can be formalized as one of a limited set of some, so to speak, standard functions. In particular, such a function may correspond to an increasing exponential. The functioning of control systems for these processes should be ensured in such a way that the reaction of the system itself to such highly probable signals is adequate and successfully formed in accordance with the criterion of minimum error. One of the ways to solve this problem is to form a parametric or additive–parametric feedback circuit in the control system, as well as integrate components with parameters changing according to a certain law into the structure of the system. At the same time, the error should not depend on the magnitude of the parameters noted above and, in fact, is minimized. The authors synthesized and substantiated models and algorithms for the functioning of control systems with parametric feedback by transmission coefficient, which make it possible to eliminate control errors and ensure the noise immunity of the system. It is also proposed to use other means that ensure the high efficiency of such systems that implement the management of objects and processes of various types.
