The Control System of a Linear PMSM in Drive of the Low-Speed Long-Stroke Reciprocating Compressor

There is a task of forming the law of motion of the piston of a low-speed long-stroke reciprocating compressor in the practice of developing and using reciprocating compressor units. The set parameters in this case are not only the amplitude and frequency, but also the possibility of setting the harmonic composition (non-sinusoidal law of piston motion). For example to the need for smooth gas injection followed by a rapid suction phase - this allows you not to overheat the compressor stage. The main feature of a linear electromagnetic motor is the direct proportionality between the force acting on the armature and the current that goes through the motor winding.
