The invention provides a rectifying tower process anti-interference control structure considering input constraint and a control method, and belongs to the technical field of chemical rectifying tower process energy-saving control. The problems of large fluctuation of product concentration and long recovery time caused by strong coupling and input constraint problems in the rectifying tower process are solved. According to the technical scheme, a control structure comprises an active-disturbance-rejection controller I with an optimization function, an active-disturbance-rejection controller II with an optimization function, a dynamic decoupling module and a rectifying tower process controlled object; according to the control method, decoupling control over product concentrations at the two ends of the rectifying tower process is achieved by designing an anti-interference control method with an optimization function. The control method has the beneficial effects that the degree of dependence of the control met
