| 摘 要： | 利用调制函数法辨识非线性连续系统的模糊模型参数.系统的动力学微分方程存在微分项,通过输入输出数据辨识模糊模型参数时不能忽略扰动的影响,因此辨识模糊模型参数比较困难.利用调制函数法可以消除微分项,通过无微分项的联立方程的求解容易进行模糊模型参数辨识.几个非线性连续系统的仿真实验验证了所设计的利用调制函数法的模糊模型参数辨识的正确性和有效性.

| Abstract: | The problemof parameter identification of the fuzzy model in nonlinear continuous system is discussed by using modulating function method. It is difficult to identify the parameters of the fuzzy model using input-output data because of the differential equations of dynamics with differential terms which result in the noise. The differential terms can be removed by using modulating function, then the parameters of fuzzy model can be easily identified from the simultaneous equations without differential terms... |
