Centralized control implementation using distributed observer for Meglev systems

Abstract

In the control of maglev systems, decentralized control structure is widely used due to its simplicity. Due to the existence of mechanical coupling, the performance of decentralized control is limited. This paper focuses on designing a centralized controller for a small maglev platform that already has a decentralized control structure. A distributed reduced-order observer is first proposed for one suspension point to estimate the state of other suspension points using the model of the system. Consequently, a centralized control is designed and implemented with the help of the proposed decentralized observer. The simulation results show that centralized control based on distributed observer ..
