Research on Software Design of DSP Motion Controller

In recent years, along with the rapid development of chip technology, foreign motion controller taking DSP or FPGA as core processor has increasingly become a development trend. This paper finishes the software design of a motion controller based on DSP. The whole system software is designed modularly, including system initialization module, interrupt module, PID control algorithm module and PWM output module, etc. The modular design of software strengthens the readability of program and favors the debugging, modification and upgrade of control system.
