摘 要：
In the research,the general structure and working principle of four-fold rotary hay dryer was introduced.Hardware and software design scheme was described,then the principle of fuzzy PID control and PID control was analyzed and the control arithmetic was simulated and studied.The results showed that the automatic control system of the forage dryer had the advantages of well stability and high control precision,and the design met the requirements of the production technology.
