An analysis technique of stability and self-oscillations in single-circuit automatic control systems with monitoring and derivative feedback is given in the article in the presence of a nonlinearities such as endplay, friction of rest, sliding friction, blanking zone, and saturation, whose characteristics are described by nonlinear homogeneous functions of the first order. The technique is based on the simplest mathematical models of the nonlinear automatic control systems, taking into consideration the main dynamic properties of the monitoring object and the controller. Exact analytical solutions are obtained due to the transition to a new generalized controlled variable, including the monitoring parameter and its derivative, and due to the similarity of the transient processes in the considered nonlinear automatic control systems. Such solutions have not been obtained in other works and are of interest for specialists on automatic control systems in different technical fields.
