The invention discloses a control method for tracking and predicting structural uniformity of threshed tobacco strips. The method comprises the following steps: calling post-beating blade structure index data and post-beating SQH1 value historical data of each batch; using data analysis software, performing correlation analysis, determining a key influence factor of SQH1 value control after beating; carrying out data processing on each batch of non-key influence indexes; determining a key influence factor quantization range by adopting a backstepping method; constructing a structure uniformityprediction model of the threshed tobacco strips; and training an optimal post-beating SQH1 value key influence factor range by utilizing historical data of post-beating blade structure indexes of each batch, introducing the optimal post-beating SQH1 value key influence factor range into a post-beating SQH1 value tracking model, and presetting and inputting index detection data of a large piece rate, a medium piece rate a
