The main priority of modern astronautics is improving fuel efficiency and increasing payload mass. Multistage aerospace air-launch systems are one of the best choices for solving this problem. The complexity of such kind complexes presupposes the organization of automatic control modes. The problem of designing a new class of autopilots becomes actual due to requirement toughening to reliability and efficiency of airborne system and expansion of the range of tasks to be solved. Method of analytical design of aggregated regulators (ADAR) was used for synthesis. The aerospace complex includes a carrier aircraft and an upper stage located on top. They are connected by three nodes, nasal and two main. The article considers the applied problem of synthesis control algorithms for the separation of the upper stage and carrier aircraft with the simultaneous breaking of all connections between them. The controller is synthesized using a full nonlinear mathematical model of longitudinal motion of the system, taking into account aerodynamic interference and forces in communication nodes between - upper stage and carrier aircraft. Demonstrated exact implementation of specified control goals.
