摘　　要：针对由质量偏心引起的无轴承异步电机不平衡振动问题,首先介绍了不平衡振动的产生机理;然后研究给出了不平衡振动前馈补偿力的实时估算调节方法和不平衡振动位移提取算法;最后对无轴承异步电机不平衡振动控制系统进行了仿真分析。仿真结果表明:利用所给补偿控制策略后,转子的不平衡振动幅度得到大幅度抑制,大大提高了转子的悬浮运行控制精度,所给不平衡振动补偿控制方法是有效、可行的。Aiming at the unbalance vibration problem of bearingless induction motor caused by mass eccentricity, the generation mechanism of unbalance vibration was analyzed firstly. Then, the real time estimation and adjusting method of unbalance vibration compensation force and the extraction algorithm of unbalance vibration displacement were researched in detail. At the end, the simulation analyses of unbalance vibration control system of bearingless induction motor were made. The simulation results show that adopting the presented compensation control strategy, the unbalance vibration amplitude of the rotor can be greatly suppressed： the suspension control precision of the rotor can be improved greatly. The presented compensation control method of unbalance vibration is effective and feasible.
