Synthesis of motion control of three-mass oscillating system based on solution of inverse dynamic problems

摘要

In the article, using the example of a three-mass oscillating system, a procedure for the synthesis of motion control is presented, based on the determination, by solving the inverse dynamic problems, of the control actions that provide the desired character of the oscillating motions for individual partial systems. It is shown that the received control actions will be functions of time, which do not impose any restrictions on the structure of controllers, which can be realized by choosing the design parameters of the control object and by using closed automatic control systems. Since the feedback gains are determined directly from the mathematical model of the control object, the control system will have a weak sensitivity to parametric and coordinate perturbations. The results of numerical simulation of the effectiveness of the proposed method for limiting elastic oscillation are presented.
