Abstract
Fully-digital PWM DC motor speed regulation and servo system was researched and designed in the paper,where a kind of master-slave computer architecture was applied and the DSP-TMS320LF2407A was chosen as the core controller.The design scheme of hardware and software was also proposed.Based on the system,a lot of experiments were done.The results demonstrated that the design of hardware and software was reasonable and practicable.Speed regulation and servo positioning could be achieved easily.
