The paper presents design of the hydraulic distribution drive based on a proportional electromagnet, physical processes in the proposed design are described. The drive mathematical model was developed based on the proportional electromagnet. Problems of the electromagnetic hysteresis presence were formulated from the point of view of the device control system. An approach is proposed describing electromagnetic hysteresis in the general case. A model of the system under consideration was compiled in the MATLAB Simulink package. A technique was proposed making it possible to neutralize the electromagnetic hysteresis influence on the system transient process, and the possibility of refusing to use the positioning sensor was justified. System operation was simulated with various input signals. Conclusions were made on the model current accuracy, and the options for its verification were considered.
