The subject of study in the article is the process of forming algorithms for controlling the angular motion of the rocker with a screw electric actuator. The purpose is to develop approaches to the formation of algorithms for controlling the angular motion of the rocker with a screw electric actuator as the automatic control object. Tasks: to specify the synthesis process of the state control algorithm for a linear mathematical description of the automatic control object in the state space according to the minimum criterion of the integral from the weighted error module. To form the block diagram of the automatic control system by the state. To improve the approach to the development of algorithms for controlling automatic control objects by output for mathematical description in the frequency domain. To illustrate the features of the approach on the specific example of automatic control object represented by transfer functions in terms of references and disturbances. To develop the simulation scheme in Simulink and study the reactions to stepwise references and disturbances. To develop the approach to the formation of control algorithms for the diagnosis of the rocker as the automatic control object. To describe the procedure and means of deep diagnosis of emergency situations of the automatic control object. To develop means of recovery the automatic control object. The methods used are the state space method, transfer function method, integral optimality criteria, methods of diagnosing, and recovering. The following results were obtained: approaches to the formation of algorithms for controlling the angular motion of the rocker with a screw electric actuator using linear mathematical descriptions in time and frequency domains were formed. Conclusions. The scientific novelty lies in the formation of approaches to the development of algorithms for controlling the angular position of the rocker with a screw electric actuator which differs from the known accounting the structural and functional features of the automatic control object.
