摘要: 伺服阀控马达装置的相关参数在其工作期间并不是恒定的,对其相关参数的识别有利于其液压控制系统的性能优化,因此伺服阀控马达装置的参数识别方法的研究具有十分重要的意义。首先,以伺服阀控马达装置为研究对象,推导出其数学模型;然后,基于数学模型;提出了一种参数识别方法;最后,以某一型号伺服阀控马达装置为例,基于MATLAB软件仿真获得该装置相关参数的时变曲线图,从而获得在一定工作周期内其控制系统的确切数学模型,为控制性能优化策略的实施提供参考。

Abstract: The relevant parameters of the servo valve controlled motor device are not constant during its operation, and the identification of the parameters of the servo valve controlled motor device is conducive to the performance optimization of its hydraulic control system. Therefore, the research on parameter identification methods for servo valve controlled motor devices is of great significance. Firstly, the mathematical model of the servo valve controlled motor device is derived; Then, based on the mathematical model, a parameter identification method is proposed; Finally, taking a certain type of servo valve controlled motor device as an example, the time-varying curve of the relevant parameters of the device is obtained through simulation based on MATLAB software, so as to obtain the exact mathematical model of its control system within a certain work cycle, providing a reference for the implementation of control performance optimization strategies.

Key words: servo valve controlled motor device, mathematical model, MATLAB, simulation
