In this paper a suboptimal algorithm for synthesis of a movable object control, based on the known approach, according to which a control is formed depending on a control error – the difference between current and required values of a regulated variables vector is considered. The distinctive peculiarity of the algorithm was based on the vector of regulated parameters estimation approach. This vector is proposed to be estimated by solving a mobile left endpoint problem derived from the original one. It is shown by examples that the proposed approach allows to simplify the control synthesis problem solution and obtain effective control algorithms, providing a suboptimal control and, in some cases, presented in this paper, an optimal control. The suggested algorithm can be used to determine continuous and pulse controls of aircrafts (including spacecrafts) in problems of their approaching (guidance) and spacecraft docking, carrying out of correcting maneuvers, descent and soft landing of spacecrafts at al.
