description The invention discloses a control method for smooth rolling of thin-gauge double-side waves of a tandem cold mill, and the method comprises the steps: in a smooth mode, an AGC control mode and a model control mode are optimized, and the optimized AGC control mode comprises a tension control mode for optimizing a machine and an emulsion adjustment control mode; the optimization of the plate shape control mode comprises optimization of a set value of a plate shape control curve. The control method is simple in optimization, low in input cost and obvious in effect, and the quality of the plate-shaped strip steel is improved; according to the control method, as the program is optimized, excessive manual intervention and adjustment are not needed; the control method is actually applied to the production process, the plate shape control is reliable, the plate shape reject ratio is greatly reduced, the double-edge wave defect of a thin-specification product is effectively overcome, and the product percent of pass is
