PurposesThe application of FESTO training system in the design of automatic control system is introduced. With the help of resarch of one example, the real industrial application of the conveying controlled automatically, one convenient design method of pneumatic electrical - pneumatic automatic control system is developed Procedures. Practice proves that using this method is a good way for learning automatic control technology and the system design. The results is also santisfied for teaching and the application. Can increase the ability and efficiency of technicians in automatic control system design. and their abilit correcting.
