数字伺服系统中行程限制问题的研究及实现

该文讨论了一套高速高精度数字伺服系统的行程限制问题，介绍了这套系统的概况，根据行程限制的指标要求把受控对象的运动区域分为限制区和制动区，从动力学的角度出发，分析了此区域内受控对象的运动特性。据此，提出相应的行程限制控制算法。工程应用结果表明，对行程限制问题的分析正确，算法简洁有效，并对伺服系统的行程限制的普遍问题肯有参考意义。

The Study and Realization of the Route Limitation of a Digital Servosystem

This paper discusses the route limitation problem of a high speed and high precision servosystem. First, the general state of this system is given. According to the limitation indices of this system, the route is divided into two parts: the limited area and the halted area. From the dynamis point of view, the movement characteristic of the controlled object is analyzed, and the controlling method is given. The result of engineering application shows that the analysis is correct and the realization is simple and effective. It serves the general reference to the servosystem route limitation problem.
