| 中文摘要 |
| 针对一种标准形式的非线性系统,以Li-xin Wang提出的模糊算法为基础,设计了一种新的自适应模糊控制器,采用直接控制器代替原有的监督控制器.根据Lyapunov 定理, 在放宽稳定性条件的前提下,证明了此闭环系统的稳定性.同时,给出了直接控制器的范围,由此可以解决由于监督控制器而可能引起的控制器的大幅波动.通过对一阶、二阶控制系统的仿真,可见本算法能大幅度提高系统的响应速度、以及其他的动态响应性能. |
| 英文摘要 |
| According to a normal form of nonlinear system, a new nonlinear adaptive fuzzy controller is proposed based on Li-Xin Wang's adaptive fuzzy system. The supervisory controller is replaced by the direct controller. The stability of the close-loop system is then proved with Lyapunov theory when the stability requirement is relaxed. The range of direct controller is also given, eliminating the intensive fluctuation in controll caused by the supervisory controller. Finally, the simulation results of a first order and a second order systems are given to show that the new controller speeds up the dynamic response and improves the other dynamic characteristics. |
