| 中文摘要 |
| 为了提高永磁型无轴承电动机悬浮系统的稳定性和抗干扰能力, 从运行原理出发,对悬浮系统提出了基于混合灵敏度的H∞鲁棒控制. 通过选取适当的灵敏度和补灵敏度加权函数, 设计了H∞控制器. 应用该控制器实现了基于转子磁场定向控制的永磁型无轴承电机悬浮控制系统. 仿真结果表明, 所提出的H∞控制器具有良好的抗干扰能力和鲁棒稳定性, 性能优于常规PID控制器. 最后进行了实验研究, 证明了该控制方法的有性. |
| 英文摘要 |
| To improve the stability and disturbance rejection for the suspension system for a bearingless motor of permanent magnet type, a mixed sensitivity robust control strategy is proposed based on the operating principle of suspension system. The controller is designed by selecting the appropriate sensitivity and complementary sensitivity weighting functions. The suspension control system for the bearingless motor with rotor flux orientation is also implemented on the basis of proposed controller. Simulation results show that the performances of the proposed controller are superior to those of the traditional PID controller with the robustness in modeling the system and disturbances. The validity of proposed algorithm is also effectively evaluated by experiment study. |
