摘要/Abstract

摘要： 通过协调电液动力源转速和排量可以提升其能效，也是目前电液动力源的研究热点，随着变频和伺服技术的发展，变转速电液动力源也越来越多地应用在工业生产和航空航天装备中。目前，电液动力源实现流量控制可以采用变排量控制，也可以采用变转速控制，这两种控制方式已非常成熟，应用也较多。但在压力控制中，还往往只能依赖液压泵变排量控制结合压力反馈实现压力控制机能，采用变转速控制压力时，难以适应负载流量随机快速变化工况。为此，提出采用高效率的伺服电动机直接驱动定量泵，进一步提出基于转矩控制和转速补偿的压力控制方案，在负载压力变化时，无需控制电动机转速，具有动态响应快、系统结构简单的优点。通过理论分析和试验研究，结果表明，采用设计的方案可以很好地实现压力控制，在相同条件下，与常规恒压变量泵相比，压力响应时间从160 ms降低到50 ms，响应速度远超国际同类恒压控制泵

Abstract: The energy efficiency of the electro-hydraulic power source can be improved by coordinating its speed and displacement, which is also the research hotspot at present. With the development of frequency conversion and servo technology, speed variable electro-hydraulic power source is more and more applied in industrial production and aerospace equipment. At present, the flow control of power source can adopt variable displacement control or variable speed control. These two control methods are very mature and widely used. However, in the pressure control, a constant pressure pump combined with pressure feedback is often used to realize the pressure control. If the pressure is controlled via the pump speed, it is difficult to adapt to the random and rapid changing of load flow rates. A high-efficiency servo motor is used to drive the quantitative pump directly, and a pressure control scheme based on torque control is proposed. When the load pressure changes, there is no need to control the motor speed, which has the advantages of faster dynamic response and simple system structure compared with the conventional constant pressure displacement variable pump. Through theoretical analysis and experimental research, the results show that the design scheme can achieve the pressure control. Under the same test conditions, compared with the conventional constant pressure pump, the pressure response time is reduced from 160 ms to 50 ms.
