摘要
提出了磁力轴承反向差动驱动控制的概念,建立了磁力轴承反向差动驱动控制的动力学模型及其状态方程。利用Matlab对反向差动驱动的磁力轴承进行了仿真研究,与常规差动驱动的磁力轴承相比,反向差动驱动的磁力轴承在超调量、调整时间和稳态误差等方面均优于常规差动驱动的磁力轴承。仿真研究的结果表明:磁力轴承的反向差动驱动控制效果不仅与轴承的结构设计参数有关,还与控制参数的选择有关。
The concept of reverse push-pull controlling for a magnetic bearing was put forward.The dynamic model and state equation of reverse push-pull controlling for a magnetic bearing were built up.The simulation study on a reverse push-pull controlled magnetic bearing was conducted with Matlab.Compared with conventional push-pull controlling for a magnetic bearing, the reverse push-pull controlling had better performance on the aspect of overshoot,settling time and steady state error.The simulation results showed the reverse push-pull controlling effect was related to structural design parameters of the magnetic bearing and was related to the controlling algorithm.
