“…In expressions ( 4) and ( 6), the parameters  and  can be determined based on the standard forms of the characteristic polynomial [24,25]. We find the control actions that implement the given laws of change of the forces in the elastic element ( 4) and ( 6) in the mechatronic system (3) by solving the inverse dynamic problem the algorithm of which is described in detail in [21]. The calculation results are presented in the form of a table 1 in which the left column corresponds to the law (4), the right one to the law (6).…”

“…An effective tool for the implementation of such an approach can be the use of the concept of inverse dynamic problems, which makes it possible to form the control of the dynamic state of mechatronic systems based on the required nature of controlled motion [20]. As shown in [21,22], the control actions obtained in the form of time dependences based on solving the inverse dynamic problems for a given form of the transient process allows not to impose any restrictions on the methods and means of their technical implementation and thereby provide a comprehensive approach to the problem of compensating dynamic errors caused by elastic deformations of mechanical elements.…”

In this paper, using the example of a two-mass calculation scheme, which can be used to describe the dynamic properties of many mechatronic systems with elastic elements, we present the results of research on finding control actions that provide compensation of dynamic errors based on solving the inverse dynamic problems according to a given law of change of the force in an elastic element. It is shown that the found control actions in the form of time dependences make it possible not to impose any restrictions on the methods of their technical implementation and thereby provide a comprehensive solution the problem of compensating for dynamic errors caused by elastic deformations of mechanical elements.

The article is devoted to the issues of reducing the dynamic loads of mining machines using elastic-damping devices built into the mechanism. It presents the results of research that determines the parameters of these devices based on the solution of the inverse dynamic problem for a given low of change of elastic force in the cable of the excavator traction mechanism. It is shown that the use of this synthesis method allows us to obtain optimal values of the design parameters of such devices that fulfill several contradictory criteria of the quality of the transition process, determined by the desired low of change of the force in the cable. Using the example of a two-mass electromechanical system that simulates the dynamic properties of a dragline traction mechanism equipped with an elastic-damping device, the procedure of the synthesis of the proposed parameters is described and the results of a numerical study of its efficiency are presented.

The paper presents the results of studies of the effect of the counter-electromotive force (CEMF) of the dc machine on the parameters of the elastic oscillation control system of a two-mass electromechanical system, synthesized based on of solving the inverse problems of dynamic in accord with prescribed nature of controlled motion. It is shown by the method of numerical simulation that taking into account the CEMF leads to an increase of the damping properties of the electromechanical system and an increase of the gains of the feedbacks on the force in the cable. A method for the selection of these gains is proposed, based on their comparison with the gains obtained in an electromechanical system without taking into account the CEMF and an approximate assessment of its effect on the nature of the transient processes.
