论文部分内容阅读
本文的基本内容是介绍“应用线性调节理论分析与设计液压系统”和“应用模拟计算技术研究较复杂系统的实时性能”。第一部分(第一至四讲):讲述建立液压系统教学模型的方法,一种是线性简化模型(用于线性分析),另一种是比较接近于实际的模型(用于模拟计算分析)。液压系统包括阀控、泵控、位置、速度、力伺服等。第二部分(第五至七讲):讲述了时域法与频率法的基本内容,并举例说明其用法,特别是第七讲的最后一例,以较复杂的多级电液伺服系统的设计与校正,较详细地介绍了利用线性调节理论来分析设计电液系统的全过程。第三部分(第八讲):介绍了模拟计算的概貌,讲述了模拟计算图的各种画法,并举例说明其在较复杂系统的实时分析中的应用。本文没有涉及,但在液压伺服控制中又占重要地位的问题和液压系统的非线性特征、非线性理论的应用,以及数字计算机的应用等。
The basic content of this paper is to introduce the application of linear adjustment theory to analyze and design hydraulic system and application of simulation technology to study the real-time performance of more complex systems. The first part (the first four lectures): describes the establishment of hydraulic system teaching model method, one is a linear simplified model (for linear analysis), the other is more realistic model (for simulation calculation and analysis). Hydraulic systems include valve control, pump control, position, speed, force servo and so on. The second part (the fifth to the seventh lecture): describes the basic content of the time domain method and the frequency method, and an example of its usage, especially the last one in the seventh case, to more complex design of multi-stage electro-hydraulic servo system And correction, a more detailed introduction to the use of linear adjustment theory to analyze the whole process of designing electro-hydraulic system. The third part (the eighth lecture): This paper introduces the overview of simulation calculation, describes the various methods of simulation calculation diagram, and illustrates its application in more complex systems in real-time analysis. This article does not cover, but in the hydraulic servo control again occupies an important position in the problem and the nonlinear characteristics of the hydraulic system, the application of nonlinear theory, and digital computer applications.
