| Abstract: | Seeing that high-precision numerical control system requires the control software to have strict real-time function, a design method for DOS-based multi-task control software is presented for numerically controlled positioner of arc-welding robot to meet such requirement. With this design method, the utiliza- tion ratio of CPU is improved by means of dynamic dispatch of all individual real-time tasks in the control system. The experiment shows that, due to the employment of multi-task strategy, the system reliability is remarkably improved as well as the control accuracy is ensured. |
