Determination of conditions for optimal control of linear magnetoelectric drive of low-speed single-stage piston compressor

Abstract

During designing a linear magnetoelectric drive (LMEP), which includes a permanent magnet synchronous driver (SDPM) and the compressor stage, much attention is paid to reliability and efficiency while ensuring high rates of energy conversion processes occurring in various subsystems. One of the areas that increase the reliability of LMEP is to reduce the number of elements included in its composition, for example, transmission and converting mechanisms. However, in this case, nonlinear suction-discharge processes occurring in the compressor stage have a significant effect on the operation of the electromechanical converter. In this connection, the task of increasing the energy efficiency of LMEP can be solved in various ways. The article describes the control conditions for the LMEP of a low-speed single-stage reciprocating compressor obtained from solving the problem of optimizing the design of the SDPM magnetic system at which maximum efficiency is achieved. The relationship of the generalized parameters of the drive with the design features of the SDPM design is established.
