摘　　要：针对高频率的大口径天线,提出了滑模伪微分反馈控制方法,既避免微分环节对噪音的敏感,同时也解决了大型天线要求不能有抖震这一问题,并增强了对不确定性因素影响的抗干扰能力。利用滑模控制器提高控制系统鲁棒性,并分析该非线性滑模控制器不会造成系统的不稳定。通过仿真和实验证明伪微分反馈控制方法具有良好的控制性能。Aiming at the controller design of antenna system, the phenomenon that differential block is susceptible to noise is avoided by the method of Pseudo-differential feedback control. Problem that large-scale antenna can＇ t chatter is solved. The system＇ s robustness is improved by using sliding mode controller. Analysis shows that this nonlinear sliding mode controller will not conduce to instability of system. Simulation and experiment results show that pseudo-differential feedback control has perfect performance.
