| 摘 要： | 针对一类多输入多输出不确定非线性系统，用一个RBF神经网络获得未建模动态和外来扰动的估计值，将回馈递推思想与滑模控制相结合，逐步回馈递推，设计了鲁捧控制器。将这种方案用于某型侧滑转弯导弹的飞行控制系统设计。其中，为克服导弹作动器的位置饱和、速率饱和问题，改进了滑动面的符号函数，并采用模糊逻辑对滑动面的斜率进行实时调整。仿真表明了该控制方法的有效性。

| Abstract: | For a class of multiinputmultioutput uncertain nonlinear system,a robust controller based on backstepping and sliding mode control was designed.The unknown dynamics and external disturbances were estimated by a RBF neural network.Then the scheme was applied to design the autopilot system of a skidtoslide missile.Considering the missile's actuator position saturation and velocity saturation,the sign function of the slide mode was improved and fuzzy logic was introduced to adjust the slopes of the sliding mode surfaces.The simulation results show its effectiveness. |
