摘要

Servo following control system is an important part of modern automatic control system. It takes various mechanical parameters as the control object to make the output variable automatically follow the change of the input variable and achieve fast and accurate effect. Nowadays, servo following control system, not only in industrial production, agricultural production or People's Daily life is widely used, but also in robot, automation equipment and other high-tech also begin to develop rapidly. Servo following control has the advantages of small following error and high precision, which can easily realize the real-time following of the rotary table. With Mitsubishi FX series, model for the selection of PLC FX3u-48 MT, due to the type of PLC with high-speed pulse input and output module, encoder through gathering information to complete the data processing, to control the servo motor, realization cross flower-stand follow wheel run to achieve relatively static state, through the programming algorithms for data migration control electromagnetic pen move to draw the corresponding design. In this paper, programmable software GX works2 and GT Designer3 are selected for programming configuration. Sequence function diagram and ladder diagram language are mainly used to complete the program, which greatly simplifies the program structure. Due to the integrated circuit inside PLC, the whole design reduces the use of ordinary relays, thus increasing the service life of the system and optimizing the system performance. With GT Designer3 touch screen configuration software, operation and monitoring elements are added to make the program run more clearly and greatly save time.
