Research on Control Strategy of Bearingless Asynchronous Motor Based on PID Controller
Bearingless Induction Motor(BIM)has important research and application value due to its advan-tages of low friction,no need for lubrication,and high operating speed.However,compared to traditional a-synchronous motors,the mathematical model of BIM is a strongly coupled,multivariate,and nonlinear high-order function,resulting in relatively complex control strategies.Therefore,this article studied a BIM air gap magnetic field orientation control strategy based on PID controller,and discussed its control principle and im-plementation method in detail.Its effectiveness was verified using Matlab simulation software,and an experi-mental platform was built based on TMS320F28335 to verify the control effect.
