The Approach to Automating the Control of the Vibrational Field of a Technological Machine

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.
