数字技术的迅猛发展,使得微处理机或计算机在电液伺服系统中得到广泛应用。近年来,开发“智能执行机构”(集成有传感器、阀和局部智能的液压缸),通常是微处理控制器,成为一项最重要的任务。M.T.Pietola 和M.J.Vilenins 指出,尽管数字控制器显然要选择数字传感器,然而,还可以采用许多其他形式的传感器。本文将着重介绍在赫尔辛基工业大学进行的试验结果。微处理机价格便宜,因此广泛应用数字型控制器取代模拟型控制器。并且数字技术给液压伺服系统带来许多优点。例如,控制
The rapid development of digital technology, making microprocessors or computers in the electro-hydraulic servo system is widely used. In recent years it has become one of the most important tasks to develop “smart actuators” (hydraulic cylinders with integrated sensors, valves and local intelligence), often microprocessor controllers. M.T. Pietola and M.J. Vilenins pointed out that although the digital controller obviously has to choose a digital sensor, however, many other forms of sensors are also possible. This article will highlight the results of the experiments conducted at the Helsinki Technical University. Microprocessors are inexpensive, so digital controllers are widely used to replace analog controllers. And digital technology to the hydraulic servo system brings many advantages. For example, control
