| 中文摘要: |
| 针对一类带有未知死区的随机严格反馈非线性系统，提出了一种自适应模糊控制方案：利用命令滤波来处理退步方法的复杂性问题，并引入误差补偿机制克服动力学表面方法的缺点；此外，通过利用死区斜坡的边界信息，对未知的非线性系统不需要建立逆死区。与已有的结果相比，该方案的优点是：通过建立补偿信号消除滤波误差，且只有一个必需的自适应参数，这使该控制方案在实际应用中更有效；该控制方案，保证了闭路系统的所有控制信号最终一致概率有界，跟踪误差收敛到相应的紧集。 |
| 英文摘要: |
| An adaptive fuzzy control scheme is proposed for a type of stochastic strict feedback nonlinear system with unknown dead zones. In this scheme, the complexity of the regression method is dealt with by command filtering, and the error compensation mechanism is introduced to overcome the shortcomings of the dynamic surface method. And the use of the boundary information of dead zone slopes makes it unnecessary to establish inverse dead zones for unknown nonlinear systems. The advantages of the proposed scheme are that the filtering error is eliminated by establishing a compensation signal, that only one necessary adaptive parameter is necessary, which makes the control scheme more effective, and that the control scheme ensures that all the control signals in the closed circuit system have a bounded final uniform probability and the tracking error converges to the corresponding compact set. |
