Problems of proportional magnet control
The article considers the issue of relevance of proportional elements of hydraulic nomenclature in modern mechanical engineering. Existing solutions in the field of proportional elements control in the hydraulic system are analyzed. Advantages and disadvantages of proportional devices when using different types of motion sources are revealed. The problems of electromagnetic hysteresis presence from the point of view of the device control system are described. Various options for reducing the effect of nonlinearity on the operation of the device are considered. A method for leveling the effect of electromagnetic hysteresis and improving the quality of transients of hydraulic proportional elements is proposed. The possibility of practical implementation of the proposed method is considered. The conclusions about the possible problems of application of the proposed method are made and the ways of their elimination are proposed.
