Developing a DSP-Based Control System of Servo Punch Press Using Model-Based Method

Article Preview

Abstract:

Servo punch press uses a servo motor to drive. It can set different stroke length and velocity according to different production requirements, and can always ensure the formation precision of the bottom dead center. It has the advantages of high efficiency, high precision and low noise, and it presents the development trend of punch press. The key point of the servo punch press development is its control system. According to the functional requirements and technical performance of the servo punch press, the general approach of the servo punch press material forming control law is discussed in this paper. The development platform based on DSP control system has built up as well. By means of the Simulink and the Target for TI C2000 tools in Matlab, the dynamic model of punch press system and controlling model, including forming model, DSP-based controller model and plant model,etc., have been designed. Base on this, the forming characteristics of different materials, forming control algorithms have been studies through simulation and virtual experiments.The controller algorithm can be transferred automatically to the target controller. This approach can reduce developing time and costs of servo punch press control system and improve developing efficiency.
