Adaptive Predictive Tracking Control of Feed for Large Radio Telescope
大射电望远镜馈源轨迹跟踪自适应控制

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.
