Abstract: The traditional drying method needs long time and much energy. In order to enhance the stoving efficiency and reduce the system’s nonlinear hysteresis interference factors, according to the textile fiber drying process characteristics, the author puts forward a stoving method based on cascade control system, and make comparisons between the traditional PID and cascade control PID by Simulink. The experiment results show that cascade control has a large increase in response time, less overshoot, and other factors than single loop PID. Realized the optimization control and improve the testing efficiency and accuracy.
