H∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System
H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...
متن کاملThree Practical Examples of Magnetic Bearing Control Design Using a Modern Tool
The use of magnetic bearing in industrial applications has increased due to their unique properties. Nowadays efficiency and predictability in handling rotors on magnetic bearings is asked with the same standard as conventional rotors on oil or roller bearings. First of all one must be aware of the special technical properties of magnetic bearing designs. The dynamic behaviour of the rotor comb...
متن کاملImportant Parameters for Small, Twin-Screw Refrigeration Compressors
This paper deals with open-shaft twin-screw refrigeration compressors in the 10 175 m3/h (10 100 CFM) range. Applications for such compressors are, for example,external combustion engine heat-pumps and transport refrigeration. The twin-screw compressor concept is discussed from following view-points; operational mode and rotor housing design drive arrangement bearings lubricants cooling volume ...
متن کاملROBUST CONTROL OF ENERGY MOMENTUM WHEELS SUPPORTED ON ACTIVE MAGNETIC BEARINGS USING H-infINFINITY LOOP-SHAPING AND o-SYNTHESIS
The main objective of this research is to improve the feasibility of Energy Momentum Wheels for satellite systems through the development of robust LTI and gain-scheduled controllers for high-speed flywheel rotors supported on active magnetic bearings. A hybrid combination between H∞ loop-shaping and μ-synthesis is used in this paper to design controllers. In order to reduce the computational c...
