摘要
为了提高液压机双驱伺服系统的控制精度,设计了一种基于位置与速度传感器反馈的协同策略,并设计了滑模变结构模糊控制器.研究结果表明:在不同转速间速率转变时通过三角函数形式完成柔性的过渡过程,满足转速的设计条件.滑块在运行过程中可迅速完成合模与回程的运动.进行加载处理时则以低速状态运行,获得理想的加载精度.该研究有助于提高液压机的控制精度,为后续的参数设计奠定一定的理论基础.
Abstract
In order to improve the control accuracy of double drive servo system of hydraulic press crank link, a cooperative strategy based on position and speed sensor feedback was designed, and a sliding mode variable structure fuzzy controller was designed. The results show that the flexible transition process is com-pleted by trigonometric function when the speed changes between different speeds, which meets the design conditions of speed. The slider faces up to quickly complete the movement of closing and returning during the loading and running phase. When the loading process is carried out, it runs at a low speed to obtain the ideal loading accuracy. The research is helpful to improve the control accuracy of hydraulic press and lay a theoretical foundation for the subsequent parameter design.
