Abstract

The article considers the task of controlling a technological vibration machine, designed for the vibration interaction of a granular working medium with details attached to the working body of a vibration machine. The computational scheme of this kind of machine is a solid body on two springs with adjustable stiffness, which can be attributed to symmetric systems that execute a flat oscillatory motion. The task of the automatic control system is to maintain the vibration field at the required level, in particular, the amplitude of oscillations under conditions of a priori uncertainty of the parameters of the vibration machine. A control system is proposed to be built on the basis of a stabilizing regulator with static adaptation, capable of performing a target function with the object nonlinearity, external perturbations and having a simple structure. The features and conditions of functioning of this regulator are considered. A demo example is given.
工业机械振动场的自动化控制方法
本文考虑了控制一台工艺振动机的任务,该振动机是为颗粒状工作介质的振动相互作用而设计的,其细节附着在振动机的工作体上。这种机器的计算方案是一个实体体在两个具有可调刚度的弹簧上,这可以归因于执行平坦振荡运动的对称系统。自动控制系统的任务是将振动场保持在要求的水平上,特别是在振动机参数先验不确定的情况下,将振动场的振幅保持在要求的水平上。提出了一种基于静态自适应稳定调节器的控制系统,该系统能够在目标非线性、外部扰动的情况下执行目标函数,并且结构简单。考虑了该调节器的功能特点和条件。给出了一个示例。
