Abstract

In this paper, Siemens PLC controller, new generation SINAMICS V90 PN servo control system and real-time communication technology are used to design a control system of the thermal simulator for closed-loop control tasks in thermal simulation control systems. The hardware configuration, communication structure, allocation of closed-loop control tasks, data acquisition mode and logic control system of the system are introduced, and through the specific control process, the main controller S7-400CPU cooperates with the FM458 controller to complete the hammer position control, the temperature control methods of the direct resistance heating method and the induction heating method, and the method and characteristics of the real-time communication between the main controller and the S7_1200PLC to control the SINAMICS V90 PN servo motor to realize deformation displacement control are focused on
