Control system and method for traction power supply system of direct current motor and related assembly

The invention discloses a control system and method of a traction power supply system of a linear motor and related components, relates to the field of linear motors, and is used for controlling the traction power supply system, and the control system comprises an upper computer which is used for transmitting a control signal comprising an operation curve through an operation control system; and a plurality of controllers for receiving control signals, each controller being used for controlling all the inverters corresponding to the one or more stator segment windings so as to form a potential difference between two ends of the corresponding stator segment winding and generate a current corresponding to the operation curve to drive the linear motor. The potential difference of the stator section winding is adjusted by controlling the output voltage of each inverter, linear motor driving is achieved, the controller can complete accurate current adjustment by controlling the inverter, current balance of the dir
