| 摘 要： | 为改善模糊系统逼近的收敛速率,提出了一种基于快速终端滑模的反向传播(BP)学习算法。将快速终端滑模引入模糊逻系统的学习算法,综合终端吸引子有限时间收敛和线性系统指数收敛的性质,提高了对非线性连续函数的逼近能力。仿真结果表明:该算法能以较快速率逼近未知函数,且逼近过程稳定,较普通学习算法更为精确和有效。 |

| Abstract: | A back propagation learning algorithm based on fast terminal sliding mode to approximate was put forward to improve the convergence of fuzzy system in this paper.The fast terminal sliding mode was introduced into the learning algorithm of fuzzy logic system.The approximate system efficiency of unknown nonlinear continuous functions was improved with convergent property of terminal attractor in finite time and exponential convergent property of linear system.The simulation results showed that this algorithm could approximate unknown functions with rapid velocity and tranquilization process,which was better than conventional method in exactitude and availability. |
| Keywords: | Fuzzy logic system Back propagation algorithm Fast terminal sliding mode Terminal attractor |
