Construction of amplitude and phase frequency characteristics of nonlinear systems.
A general method for determining the frequency characteristics of open-loop and closed, single and multi-loop non-linear control systems is considered. The method of reducing all linearization coefficients of non-linear links to functional dependence on a single signal is used. at the input of a closed system from the value of the frequency and the values ??of fixed errors. Methods of reducing the characteristics are considered characteristics of the individual circuits of the system to certain values ??of the input signals.
