(.):  In this paper we consider the problem of synthesis of automatic excitation control system (AECS) on the channel of angular speed stabilization of the synchronous generator rotor stabilization. The features of AECS should include limitations of minimum and maximum excitation, excitation rate of change, excitation forcing, swing damping, and stabilization of own and group motion. To solve this problem, the method of expanding the state space by introducing first-order filters into the feedback circuit is used. When the system is subjected to external disturbances, the use of deep feedbacks based on linear functions with saturation makes it possible, on the one hand, to solve the problem of tracking the output variables with a given accuracy and, on the other hand, to provide restrictions on the phase variables and controls. To obtain estimates of the unknown components of the system state vector and the uncoordinated external perturbations acting on the system, an observer is constructed on sliding modes. The results of numerical simulation in Matlab confirm the high efficiency of the proposed approach to the synchronous generator control.
