【摘要】 本文在普通液压缸和一组通用节流阀的基础上 ,设计了用于控制磨床工作台升降装置运动的计算机控制系统。该系统通过控制多个具有一定开口面积比电磁节流阀的通断组合 ,实现对升降装置运动规律的控制。由于采用了快速启动、匀速前进和缓慢接近目标点的运动规律 ,大大减小了目标点处惯性对工作台位移精度的影响 ,并通过自学习和微调控制策略实现了工作台任意位移量的精确控制更多还原

【Abstract】 An approach of improving general grinding machine by computer was presented and the PC-based control system was designed in this paper. Computer control system for displacement of worktable of plane grinding machine is designed by using usual fluid cylinder and a set of general throttles in this paper. This system can control worktable to move according to definite moving disciplinarian through controlling electromagnetism throttle with definite opening area to open or close. By fast startup, even velocity moving and slowly near target point, the influence of inertia can be deduced, and the displacement precision can be increased greatly. The precision control of arbitrariness displacement of worktable can be realized by the self-studying control principle and slender adjustment strategy.更多还原
