Abstract
A control system based on TMS320F2812 DSP chip was developed in paste extrusion experimental device to investigate the intermittent paste extrusion process. The software of control system was designed to control the actions of step motor in this device. The upper computer (PC) software with interactive interface can input the parameters and collect the extrusion force data. The commands and instructions were sent to lower computer (DSP F2812 control system) through RS232 serial interface. The transmission data content was divided into three parts (upper 4 bits, middle 6 bits and low 6 bits) to avoid incomplete data between sixteen-bit peripheral bus and eight-bit registers in SCI module. The lower computer software includes main program and initialization module, motor driving module, interrupt module, communication module, A/D converting module. The DSP chip calculates the control instructions and parameters and drives the motor to execute the required actions. The actual tests showed that the running of control system software was reliable.
