| 摘 要： | 新一代大射电望远镜（LT）馈源指向跟踪系统具有变结构、非线性、慢时变、大滞后、强耦合、多输入多输出的特点，根据生物免疫系统反馈机理，在分析了常规PID控制和模糊控制算法的基础上，提出了用模糊控制器自动调整免疫系统反馈规律的免疫PID控制器来实现馈源轨迹跟踪的策略。对LT馈源指向跟踪系统的数值仿真实验结果表明，当存在外界随机扰动时该控制算法不仅能满足对馈源轨迹跟踪精度的要求，而且控制系统具有较强的鲁棒性。

| Abstract: | The feed-supporting system for the new-generation large spherical radio telescope (LT) has the characteristics of variable structure, nonlinearity, slow time-variant, large delay, strong coupling and MIMO (multi-input/multi-output). Based on the immune feedback mechanism of biological immune systems and the performance analysis of conventional PID control and fuzzy control, an immune PID controller, which uses fuzzy controller as anti-body-suppressed function to improve the self-tuning capability, is utilized to realize the trajectory tracking of the feed. Simulation results obtained for the feed-supporting system with stochastic disturbance have shown that the tracking accuracy is much better than the conventional PID controller and the feed-supporting control system has strong robustness. |
