Elastic power control method for chassis driver of four-wheel independent electrically-driven robot

The invention discloses an elastic power control method for a chassis driver of a four-wheel independent electric-drive robot. The elastic power control method comprises the steps that the four-wheel independent electric-drive robot receives an advancing instruction sent by a remote controller; respectively setting expected current of the four paths of driving units according to the requirement of an advancing instruction; calculating the junction temperature of the power device in real time through a junction-shell heat network model, outputting the junction temperature to a temperature closed-loop fuzzy controller, adaptively adjusting temperature closed-loop control parameters, and dynamically outputting a current limit value of each driving unit; a current setting strategy is formulated in combination with a finite-state machine principle, and the actual current limit value of each path of driving unit is corrected; the operation current of the chassis driver is changed through current closed-loop control
