| 摘 要： | 根据高超声速飞行器的欧拉近似离散模型,提出基于Back-stepping的模糊离散自适应控制器设计方法.结合模糊自适应控制和反馈线性化的方法,Back-stepping设计的每一步虚拟/实际控制量对系统非匹配的不确定性都能进行较好补偿.稳定性分析表明,该控制方法能够保证系统跟踪误差和模糊自适应参数误差是一致终值有界的.仿真使用了高超声速飞行器的纵向模型对算法进行了验证,得到了满意的控制效果.

| Abstract: | A fuzzy discrete adaptive control method via back-stepping design is proposed for the hyperson- ic aircraft by using its Euler approximation discrete model. By combining the fuzzy adaptive control and feedback linearization, the mismatched uncertainties can be well compensated by designing a corresponding virtual/actual control input in each back-stepping design procedure. Stability analysis shows that the proposed scheme can guarantee the uniform ultimate boundness of the system tracking errors and fuzzy weight estimation errors. The longitudinal model of a hypersonic aircraft is used to demonstrate the effectiveness of the proposed strategy. |
