| 摘 要： | 针对航天器上太阳帆板这种悬臂外伸薄板结构的挠性附件 ,在存在建模参数不确定及外部扰动条件下所引起的振动 ,本文采用压电致动片作为执行器 ,将变结构控制应用于板的主动振动控制。通过仿真研究结果与应变律反馈控制比较 ,可知变结构控制具有较强的鲁棒性 ,同时控制器结构简单 ,易于实现

| Abstract: | Some flexible appendages of spacecraft are cantilever plate structures, a variable structure control method is applied to suppress the vibration due to the parameter uncertainties and environmental disturbances, and piezoelectric ceramics is used as actuators. The simulation results to be compared to that of the rate feedback control can know that variable structure control shows good robustness,and the structure of controller is simple and easy to be realized. |
