航天器非脆弱控制理论及应用研究进展

With the gradual implementation of aerospace engineering, spacecraft are developing towards high-speed, large-scale, and multifunctional large-scale and complex directions. Strong and non-fragile high-precision and high-stability control technology is an effective guarantee to ensure the normal operation of spacecraft in complex space environments and the successful implementation of space missions. This article reviews the origin and development of non-fragile control theory, and summarizes the application of robust non-fragile controllers based on linear matrix inequality (LMI) methods in spacecraft orbit and attitude control. Further explain the design methods of non-fragile state feedback controller, output feedback controller, disturbance observer, and intermediate state observer are further explained under the conditions of considering additive and multiplicative perturbations. And prospects for the development and application of non-fragile control methods are provided for future spacecraft, providing thinking for the research and exploration of robust non-fragile control methods for spacecraft, in order to meet the increasingly complex requirements of high-precision and high stability control tasks for spacecraft.
