For the demand of high speed and high accuracy, the use of active magnetic bearing (AMB) plays a key role in various industries such as clean rooms, compressors and satellites due to their contactless nature. In this research, two other control options for high speed machine were designed based on the optimal output feedback and H∞ output feedback control methods to improve the radical and axial position regulation of AMB. The output feedback control gain matrix with the minimum performance index is obtained by solving the Riccati equation and fed back to the system in order to achieve the system's performance. The above designed controllers can efficiently regulate the radial and axial directions position deviation of for AMB systems. Simulations for the two control methods were carried out using Matlab and Simulink for AMB system models. Results show that the H∞ output feedback controller has a better position deviation control performance over the optimal output feedback under condition of decreasing the disturbance of reaction. Finally, simulations results demonstrate that the H∞ Output Feedback is effective. © 2013 ACADEMY PUBLISHER. |
