The design of the magnetic suspension control system cargo platform

Abstract

Background: The paper discusses the features of building a control system for an electro-magnetic suspension of a cargo platform. The operating conditions of cargo systems are associated with a large range of changes in the mass of the cargo and an abrupt change in the voltage of the power source. The control structure of the electromagnetic suspension system contains a non-linear unstable object (electromagnet). This greatly complicates the management process. Aim: The aim of the work is to study the properties of an unstable control object for its representation by an equivalent linear model, which makes it possible to automate the process of controller synthesis in the MATLAB software environment. Methods. The main research methods are computer modeling, computational studies, analysis of research results. Results: An approach to the construction of an adaptive control system for an electromagnetic suspension based on the synthesis of a linear controller based on an equivalent linear model of an unstable object is proposed. Conclusion: The practical significance lies in the fact that the proposed approach can be used to design a control system for the electromagnetic suspension of a cargo platform.
