Furthermore, approach and a frequency-domain vibration suppression a feedback control using the accelerometer attached on the end control technique are developed in this study for the of beam was realized. In practical applications, the additional flexible beam driven by a permanent-magnet synchronous sensors and available parameters requirements make this motor (PMSM). The embedded system identification technique to be difficult to be implemented. technique efficiently identifies the resonant frequency in This study develops the system identification technique for velocity and position loops, separately, and the notch filter resonant and vibration systems, which can be easily embedded can be designed and to be integrated into to DSP-based in the PMSM driver using TI DSP F2812 chip as the PMSM driver.
