| 中文摘要 |
| 针对大射电望远镜悬索馈源为一非线性慢时变多变量耦合的系统特点, 提出用多变量极点配置自校正预测控制器 (MPSTPC)来实现馈源轨迹的跟踪控制. 建立了悬索 馈源系统的数学模型, 在有随机风扰动和无随机风扰动的情况下, 进行了数字仿真. 结果表明, 该控制算法可以很好地满足馈源系统轨迹跟踪高精度要求. |
| 英文摘要 |
| Being encountered to the characteristics of nonlinearity, non stationary and multivariable coupled feed system of next generation large spherical radio telescope (LT), an adaptive control method based on multivariable pole assignment self tuning predictive controller (MPSTPC) is utilized to realize the trajectory tracking of the feed. The model of the feed cable system is developed, and the simulation of the proposed control method is carried out with and without random wind disturbance. The simulation results have shown that the tracking accuracy is much better than that of self tuning regulator. |
