Modeling of self-oscillations in discrete distributed system with cavity resonator by method of integral equation of motion

In the article the method of modelling of self-contained generators with concentrated active two-terminal networks and distributed cavity resonators, based on the presentation of the motion equations in the form of non-local Volterra integral equation and its numerical solutions. It is shown that at formulating the integral equations of motion it is necessary to take into into consideration the capacity of the package of two-terminal network. The example of modelling of self-oscillations in the generator with the rectangular resonator at sectionally non-linear approximation of Volt-Ampere characteristic of the two-terminal network.
