本文介绍一种具有软反馈的机液速度系统的优化设计方法,它是以过渡过程单调为约束条件,以过渡时间最短为优化指标。文中给出了最佳的数学模型的优化曲线,并给出了各参数的设计计算公式。此法比过去的韦氏曲线法要好,因为后者繁琐、盲目性大,而且难以找出最佳参数。 In this paper, an optimization design method of liquid-liquid velocity system with soft feedback is introduced. It is based on the monotonous transition process as the constraint condition and the shortest transition time as the optimization index. The optimal curve of the mathematical model is given in the article, and the design and calculation formula of each parameter is given. This method is better than the previous Wechsler curve method, because the latter is cumbersome, blindness, and difficult to find the best parameters.
