Stability estimation characteristics of the system with electrodynamic link under vanishing internal resistance parameter
The article presents the results of the study of stability of systems with backward negative and positive communication. The method of assessing the sustainability of specific classes of transfer functions. Determined variants of sequences of operation modes of the system of the continuous changes of internal resistance. Considered the issues of assessing the sustainability of the system when the aspirations of the parameter of internal resistance to zero for certain types of transfer functions where the object of the study is electrodynamic support. There are multiple thresholds viscous resistance, which will ensure the sustainability of the system taking into account different set of parameters that characterize the system. It is proved, that the stability of the system can be evaluated without the account of the present rigidity. For some systems with the coefficient of viscous resistance to zero there is a transition in unstable state, or the change of the coefficient of viscous resistance may not put the system in an unstable state. In the continuous change of the coefficient of viscous resistance system with transfer functions are various modes of operation. The sequence of the various regimes is determined by the parameters of the system.
