Optimization of mechatronic drives motion laws for automated equipment

Abstract

Abstract At present, when designing mechatronic cyclic drives the developer as a rule chooses the law of motion, specifying as input data, the cycle time and the amount of movement and often introducing restrictions, for example, on maximum acceleration in case of developing high-speed drives. However, this approach leads to an overestimation of the maximum drive power and, as a result, a significant increase in energy consumption. In this paper it is shown that by choosing a rational law of motion of the drive at the stage of equipment design, it is possible to achieve a sufficiently effective optimization according to various criteria. The efficiency of optimization of different motion laws of cycle drives according to various criteria is analyzed. The dependences between the maximum instantaneous power, the amount of movement, the speed and energy consumption are established and graphically presented confirming the effectiveness of the rational choice of the law of motion parameters under an inertial load. At the same time, it is shown that when synthesizing the law of motion, it is necessary to take into account the maximum possible number of parameters so that the improvement of some parameters does not lead to a decrease in other parameters.
