Synthesis of Nonlinear Control Devices with Additive Parametric Feedback

When a control facility operates in an aggressive environment and it is characterized by a wide range of changes in a set of parameters, in particular, the transmission coefficient, and if it is necessary to ensure a high level of stability of its operation, for example, through the high-quality implementation of control processes for this facility, it is appropriate to use the principles and methods of adaptation of control systems. Such adaptation to the effects of a variety of parametric disturbances and their relief are possible due to the integration of additive and parametric feedback circuits into the control system. At the same time, as a rule, it is necessary to ensure that some criteria for the quality of management are met, in particular, the minimum error in the implementation of managerial actions. The authors of this scientific study have developed and substantiated a number of scientific provisions regarding the effective use of additive and parametric feedback subsystems in complex multidimensional hierarchical control systems. Other means of minimizing errors in the management of nonlinear systems and processes of various types are also proposed and justified.
