Abstract

The invention discloses a vortex machine axial force tracking method and system. The vortex machine axial force tracking method comprises the following steps that an electromagnetic probe is arranged in a vortex machine, and the electromechanical parameters of the vortex machine are obtained; an original theoretical target curve of the electromagnetic force is established, and electromagnetic force tracking control is carried out by taking the original theoretical target curve as a target; the exhaust flow of the vortex machine and the current of a spindle motor are obtained when the original theoretical target curve is tracked; partitioning is carried out, the initial magnitude of the electromagnetic force in the partitions is obtained one by one, the exhaust flow and the spindle motor current are recorded, and the feedback exhaust flow and spindle motor current signal change rule is analyzed; and according to the feedback exhaust flow and the current signal change rule of the spindle motor, the electromagnetic force target values of all the partitions are corrected one by one, and a new most-adaptive target electromagnetic force curve is generated. According to the vortex machine axial force tracking method, the original theoretical target curve of the axial electromagnetic force of the vortex machine under a preset working condition is corrected and optimized according to a feedback signal.

Description

technical field [0001] The invention relates to the technical field of scroll machines, in particular to a method and system for tracking the axial force of a scroll machine. Background technique [0002] Scroll compressor is a new type of volumetric compression compressor. The compression parts are composed of movable scroll and static scroll. It has simple structure, less wearing parts, small volume, high reliability, high mechanical efficiency and low noise. Excellent thermodynamic and mechanical properties. The structure of the compression chamber of the scroll compressor is composed of a moving and static scroll, and the working diagram of the moving and static scroll is as follows: figure 1 . During the working process, the fixed scroll is fixed on the frame, and the moving disk is driven by the eccentric shaft and controlled by the anti-rotation mechanism, and rotates in a plane with a small radius around the center of the base circle of the static disk. The gas is...
