【摘要】 针对望远镜影像稳定系统中的镜片驱动装置,在分析研究了外力干扰与模型参数不确定性等因素的基础上,针对抖动信号无法事先确定的特点,提出了一种不确定性补偿鲁棒控制策略,通过状态反馈控制器,克服不确定性扰动的影响,保证系统的鲁棒性。仿真结果表明,该控制方法保证了系统准确地跟踪输入信号,并有效降低了扰动和参数变化对系统性能的影响,提高了镜片驱动装置的伺服性能和鲁棒性。更多还原

【Abstract】 For the Anti-Shake system of telescope,on the basis of the analysis of the uncertain factors such as disturbances and parametric changes of the system,to the feature that the vibration signal is unlikely to predict,a uncertainty compensation robust control strategy is proposed in this paper,considering the vibration signal as an equivalent disturbance,to overcome the uncertain disturbances and ensures the better robustness of the system through a state feedback controller for the general system.The simulation results show that the control scheme can ensure accurate tracking performance,and also reduce the influence of the disturbances and parametric changes;therefore,the servo performance and robustness of the system are improved greatly.更多还原
