1、引言微处理器已成功地应用于一系列不同复杂程度的液压控制系统。1978年马斯克里(MASKREY)就在一篇论文中将电液微处理器技术分成以下五类: ·闭环伺服控制——用微处理器取代传统的电模拟量构成闭环电子装置。·环前及外围处理——信息在传统的闭环伺服控制之前或之后进行处理。·自适应控制——由信息来调整一个闭环控制过程。·灵活的多余度技术——用较高级的思考能力改进多余度液压系统。·改进的时间最优控制——增强的开关式控制。这些分类大体上是基于有关闭环伺服控制
1, Introduction Microprocessor has been successfully applied to a series of different levels of complexity of the hydraulic control system. In 1978, MASKREY included in a paper the electro-hydraulic microprocessor technology into the following five categories: • Closed-loop servo control - the use of microprocessors to replace the traditional electrical analog closed-loop electronics. Ring front and peripheral processing - The information is processed before or after the conventional closed loop servo control. Adaptive Control - Information is used to adjust a closed-loop control process. * Flexible redundancy technology - with more advanced thinking ability to improve excess hydraulic system. Improved Time Optimal Control - Enhanced On-Off Control. These categories are largely based on closed-loop servo control
