| 摘 要： | 传统的永磁型无轴承电机悬浮力控制系统由于数字控制器采样周期、电流调制过程中的延时以及电机定子铁心涡流等因素的影响,实际的可控悬浮力与其指令信号之间存在延时,因而电机的悬浮性能受到影响.基于经典控制理论中的前馈控制思想,提出了永磁型无轴承电机悬浮力前馈控制系统.仿真研究表明,该系统能够有效地消除力延时和提高电机的悬浮运行性能.

| Abstract: | Due to the time delay between controllable levitation force and its command,caused by sampling period of digital controllers,delay in current regulation and eddy current in iron cores,the performance of the conventional suspension control system of the permanent magnet type bearingless motor is influenced.Based on the theory of feed forward control,a feed forward control system of levitation force for permanent magnet type bearingless motor was proposed.Simulation study verifies the effectiveness of the pro... |
