چکیده
This paper presents a theoretical and experimental study on controller design for the AMBs in small-scale flywheel energy storage system, where main goals are to achieve low consumption improved rotordynamic stability. A H-infinity optimal control synthesis procedure is defined permanent-magnet-biased AMB-rotor system with 4 degrees of freedom. Through choice weighting functions, notch filter characteristics incorporated within reduce AMB current components caused by rotor vibration at synchronous frequency higher harmonics. Experimental tests used validate methodology provide comparative results performance efficiency. The show that able stable levitation power more than 40% (from 4.80 2.64 Watts) compared conventional PD method. Additionally, can prevent vibrational instability nutation mode, which prone occur when operating high rotational speeds.

Design, Modeling and Control of Magnetic Bearings for a Ring-Type Flywheel Energy Storage System
This study is concerned with the magnetic force models of magnetic bearing in a flywheel energy storage system (FESS). The magnetic bearing is of hybrid type, with axial passive magnetic bearing (PMB) and radial hybrid magnetic bearing (HMB). For the PMB, a pair of ring-type Halbach arrays of permanent magnets are arranged vertically to support the rotor weight. For the HMB, a set of ring-type ...
متن کاملA Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid
The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...

Characteristics of superconducting magnetic bearings for 50kWh-class flywheel system
We are developing a 50 kWh-class flywheel energy storage system as a national project, using a new axial superconducting magnetic bearing (Ax_SMB) technology. The project has started in FY2005 and will continue to FY2007. The Ax_SMB is composed of Fe core and superconducting coil, which are simply torus-shape. It generates strong restoring force in axial direction. It can realize non-contact le...
متن کاملEnergy Saving Robust Control of Active Magnetic Bearings in Flywheel
The paper reports on the investigation and development of the flywheel device as a energy storage system (FESS). The FESS is designed to operate in a vacuum and is supported on a low energy controlled active magnetic bearings (AMBs). The goal was to design and experimentally test the self integrated flywheel conception with a smart control of the flywheel rotor magnetic suspension. The low powe...
