Objective of the study was to develop a software application for the synthesis of adaptive control over the biomechanical system that would enable to form the pattern of object movement from the startup phase state, characterized by a deviation from the specified software parameters, to the final state required by the kinematic parameters.
Methods and structure of the study. The research methods applied during the study were as follows: system-structural analysis of movements, theory of automatic control, simulation of motions with a computer. The object of study was the adaptive control over the biomechanical system, driving the object of movement from the given startup state to the required final state. Materials: computer model of the movement, organization of research - computational experiments conducted on the basis of the original software program (algorithmic programming language VisualBasic 2010 Express, integrated programming environment - VisualStudio 2013).
Results and conclusions. The computational experiments showed that the adaptive control model built on the feedback law in the controlled phase coordinates and time successfully solves the problem of putting the object of movement with "erroneous" trajectory back on the given programmed trajectory with the achievement of the required kinematic parameters by the final time.

Keywords: physical exercise, motor action, adaptive control, biomechanical system trajectory.
