New System Identification Scheme Of AMB Rotor System Considering Sensor And Actuator Dynamics

This paper presents an improved identification scheme of AMB rotor systems including sensor and actuator dynamics. First, this paper discusses the necessity and synthesis of the fictitious proportional feedback gain (FPFG). The identification error due to over-parametrization of the MIMO system via a SIMO modeling is minimized using an optimal FPFG. Second, the identification procedure becomes simple and efficient through estimating system poles and zeros simultaneously. Third, more improvement in the identification is achieved through separate parameterization of the additional dynamics. The identification performance is verified with several simulations. Finally, the proposed identification scheme is compared with previous identification methods using experimental data.
