| 摘要: |
| 针对控制力矩陀螺引起的微振动问题，研究了基于磁流变阻尼器的控制方法。在磁流变阻尼器结构设计的基础上，建立了磁流变阻尼器的动力学模型，提出磁流变阻尼器的半主动控制算法。根据磁流变阻尼器对磁场的要求设计了磁路结构，在Maxwell中完成磁力线和磁感应强度的有限元分析，对系统的振动抑制效果进行了模型仿真。根据所提出的半主动控制算法及基于控制力矩陀螺平台的系统运动方程，在扰动源的激励下通过simulink进行仿真，并搭建了磁流变阻尼器振动实验平台测试其振动抑制效果。仿真及实验测试结果表明，所设计的磁流变阻尼器有效地实现了对控制力矩陀螺微振动的抑制目的。 |

| Abstract: |
| To restrain the interference of micro-vibration caused by Control Moment Gyroscope, a new control method based on Magnetorheological damper was proposed in this paper. A mechanical model based on the structure of the presented design was built, and the semi-active control algorithm of damping force was proposed for the designed Magnetorheological damper. The magnetic flux density and other magnetic field parameters were considered and analyzed in Maxwell, and also the related hardware circuit which implements the control algorithm was prepared to test the presented design and algorithm. The results of simulation and experiments show that the presented Magnetorheological damper model and semi-active control algorithm can complete the requirements, and the vibration suppression method is efficient for Control Moment Gyroscope. |
