Robust μ Synthesis Control Design for a High Speed Integrated Motor/Compressor System Supported by AMBs
Active magnetic beatings(AMBs)have been gradually adopted in high-speed rotating machinery applications and the control design plays a critical role in AMB systems.The μ synthesis control is one of the most sophisticated robust control design methods and it considers both robust stability and performance.The resulting controller is able to handle uncertainties in the dynamic system and achieve required performance and stability margin,which makes it an ideal solution for AMB control problems.However,since synthesis control design directly depends on the dynamic model,an accurate modeling process of the AMB system needs to be performed prior to the controller design.In this research,we apply the robust synthesis control design to a high speed integrated motor/compressor system supported by AMBs.It briefly describes the modeling of the test rig,summarizes the μ synthesis control design process and presents the control simulation results.The simulation results have shown that the designed μ synthesis controller is able to achieve strong control performance as well as strong robustness for the analyzed AMB system.
