Abstract: The traditional sequential execution architecture of control software for synchronous servo control systems has the problems of poor generality and expansibility, low efficiency, long running time and low precision of periodic function execution cycle. Based on the time slice polling task scheduling algorithm, a new general architecture for the control software was proposed. The scheduling management function was run in the main function, which does not occupy
the interrupt program time, and the total number of interrupt cycles executed on a scheduling task was counted, which improved the accuracy of the task scheduling cycle time. A scheduling method was proposed to avoid congestion caused by uploading multiple cycle information at the same time, by setting the delay time of uploading for the first time. It shortened the running time of the control software interrupt service program, solved the problems such as the inaccurate cycle time of cycle information upload and the congestion of multiple uploads in original sequential execution architecture control software, and improved the universality and expansibility of the control software.
