Windows下变时间步长控制在速率转台控制中的应用

Application of Various Sampling Control in Windows System for Rate Simulator

鉴于W indows操作系统在伺服控制系统中的广泛应用,针对W indows操作系统非实时的局限性,提出一种在W indows环境下通过查询实际的时间来进行速率转台控制的方法,以提高转台的瞬时速率精度和平均速率精度。文中采用了变时间步长方式控制转台的运动速率,与定时间步长的控制算法相比具有更好的瞬时速率稳定性,尤其在速率比较大时精度有大幅度提高。

According to the broad application in the windows operation system in servo control system, this thesis presents a method to reduce the non-real-time limitation of the windows operation system, which shows a method by checking the real time in windows environment to control the rate simulator, finally to improve the instantaneous rate accuracy and average rate accuracy. This thesis adopts a method by various sampling to control the rate of the simulator, the instantaneous rate stability is better than that of single sampling, especially the accuracy is more improvement in high rate.
