中文摘要：

为解决某型飞行器的角度跟踪控制问题，设计了离散模糊滑模角度跟踪控制算法。以飞行器在空间的姿态运动方程为基础建立了其短周期运动模型。基于离散时间模糊滑模算法，设计了双入双出的模糊控制器，将滑模切换函数及其变化率作为模糊控制器的输入，以模糊控制器的二维输出信号为依据调整滑模趋近律的参数，该算法在减小了系统的抖振同时，保持了控制器对模型不确定和外界干扰的不敏感性。仿真表明，该跟踪控制算法动态响应快，具有良好的跟踪性能和较强的鲁棒性。

英文摘要：

Discrete-time fuzzy sliding-mode control algorithm is proposed to solve the problems of angle-following control for a specific aircraft. The model of short-period dynamics based on the attitude equations is given firstly. And the fuzzy controller for double-in-double-out is designed, in which switch function of sliding-mode and its change rate are used as the input of fuzzy-logic controller, output are used to regulate the approximation law of sliding-mode. This algorithm can reduce chattering of system and make the angle-following controller is insensitive to the model uncertainty and disturbance. The simulation results reveal that the angel-following control has good tracking quality and robustness.
