| 摘 要： | 针对机械传动方案决策系统难以建立准确数学模型的特点,提出了利用BP及BP改进神经网络的非线性映射能力,进行机械传动方案决策系统模型辨识建模的新方法.介于网络的输入输出数据难以精确描述的特点,运用模糊理论对其进行了处理.通过仿真实验验证了利用BP及BP改进网络建立其决策模型的可行性,表明了BP改进算法收敛速度更快,模型更准确,从而为机械系统传动方案的决策提供了一种更为有效的推理模型.

| Abstract: | The paper analyzes the difficulties of the mathematical modeling of mechanical drive type decision system.A novel method is proposed that uses BP and improved BP network to identify the mathematical model of mechanical drive type decision system.The input and output data are dealt with by using fuzzy theory.The possibility of modeling of mechanical drive type decision system using BP and improved BP network is verified by the simulation experiment.The results show that the converge speed of the improved algorithm is faster.A better reasoning model is presented for the decision of mechanical drive type. |
