Abstract: An electrode thickness control method and a control system is provided. The control method includes: obtaining an initial thickness and a target thickness of a to-be-rolled electrode; controlling, according to the initial thickness and the target thickness, a target device to roll the to-be-rolled electrode; obtaining first thickness change data of the to-be-rolled electrode, second thickness change data of a rolled electrode formed through rolling, and current rolling speed data of the target device; and adjusting, according to the first thickness change data, the second thickness change data, or the current rolling speed data, a current rolling pressure or a current rolling temperature of the target device, to cause a thickness of the rolled electrode to reach the target thickness.
