碩士 === 國立中央大學 === 機械工程學系 === 107 === In this paper, the current amplifier EM19-28030-A02 manufactured by Kollmorgen and the MOSFET driver board were used to realize the control of the bearingless centrifugal pump. The PID controller was designed in the position loop and the current loop to control the magnetic bearing system. The PI controller, the disturbance observer, and the feedforward compensator were used to control permanent magnet synchronous motor. Reached the rated speed in the no-load state. In the experiment, the digital signal processor TM320F28335 produced by Texas Instruments was used as the core processor, and Code Composer Studio was used as the software compilation development environment to introduce the control algorithm into the bearingless synchronous motor system. The experimental steps were as follows: firstly float up the magnetic rotor, and then issue the speed command to run to 3000 rpm. Then introduce another set of more robust position PID controller parameters in Gain Scheduling mode, and analyze the rotor trajectory-control current relationship.
