Control systems with thyristor converters

The article discuses systems whose control circuit contains thyristor converters or a special type of indirect control system. An example of constructing self-oscillations in a system describing the behavior of electrical devices using such elements in a control loop is given. The criterion of orbital stability and the method of synthesis of stabilizing controls are proposed. The conditions for the existence of orbital asymptotic stability and Lyapunov stability for periodic solutions with a given period are presented. A control loop has been synthesized that ensures the existence of such solutions. Examples of self-oscillations are given for structurally linear systems. Solutions for self-oscillations of a given period are constructed.
