Cooperating systems, while working toward the same goal, often are characterized by different dynamic properties. The result in such a situation is determined by the component with the worst specifications or is not attainable at all. Therefore, there is a need for some corrective measures. This article suggests a variant of solving this problem based on the submission of discrepancy of the dynamic properties of subsystems in the form of a measured disturbance. Known methods of synthesis of optimal control that takes into account measurable disturbances in the framework of linear-quadratic-Gaussian representations leads to the solution high-dimensional two-point boundary value problem that requires large computational problems. The study used a new approach to control synthesis that takes into account measured disturbances without expanding the state vector using a local optimization. On the basis of this was obtained computationally economical law of control allowing to take into account the discrepancy of the dynamic properties without solving two-point boundary value problem. An example of a joint operation of the system: «intensively maneuvering aircraft - inertial tracking goniometer» confirmed the high efficiency of the proposed method of accounting for the discrepancy of the dynamic properties of the subsystems in the process of their functioning in complex technical systems.
