The invention relates to a mining dump truck variable current driving control system and algorithm, and belongs to the technical field of engineering machinery, the control system is composed of an engine, a synchronous generator, a rectifier, an excitation controller, a resistance grid, an inverter 1, an inverter 2, an alternating current asynchronous motor 1 and an alternating current asynchronous motor 2, after a three-phase alternating current output by the excitation controller is rectified by the rectifier, the asynchronous motor is controlled by the inverter, and the resistance grid is connected with the rectifier. According to the algorithm, a full-speed-domain high-performance vector control strategy is used, full-speed-domain flux linkage observation and high-performance current decoupling control are carried out on an alternating-current asynchronous motor, and electric drive system joint optimization control based on working condition recognition is carried out on the basis of a maximum torque field weakening control strategy. According to the invention, the vehicle obtains an excellent vehicle speed control effect, the driving is more comfortable and stable, and the operation performance of the mining dump truck is improved.
