- ( 3 ) for a kind of general discrete nonlinear system , a new scheme of fuzzy adaptive controller with globally stability is proposed , based on new parameter adaptive law of the system . owing to no need of the assumptions " x falling in a compact set " or " the base function being persistence excitation " which are difficult to be gotten and verified in reality , this result precedes the former research work
( 3 )本文在没有通常采用的，但在实际中难以获得和验证的“ f ( x )的定义域在紧集中”或“模糊基函数满足持续激励”条件下，针对一类一般的离散非线性系统，基于新的系统参数自适应律，给出了一种离散系统自适应模糊控制器的设计方法，证明了算法的全局稳定性 - A soft sensor modeling algorithm based on improved fuzzy neural network is presented . the normalized average output membership functions are defined as fuzzy basis functions for defuzzification calculation . in order to improve the property of convergence , some parameters of the fuzzy neural network are trained by levenberg - marquardt algorithm , and the others are trained by gradient descent algorithm
提出了一种改进的模糊神经网络软测量建模方法，采用规则化的平均输出隶属度函数作为模糊基函数进行反模糊化运算；在训练网络时，部分参数采用levenberg - marquardt算法来训练，另一部分采用一阶梯度下降法。 - It is difficult to design a traditional controller for some nonlinear systems , as some parts of the system are unknown . in this dissertation , the fnn and the traditional controller are combined to design two kinds of fnn adaptive controllers for a class of nonlinear plant . they are stable indirect adaptive controller based on fuzzy basic function network and stable direct adaptive controller based on t - s fuzzy neural network
由于传统控制器本身的局限，它们在非线性控制系统的设计和应用中存在许多问题，本文将模糊神经网络和传统控制策略相结合，设计了两种模糊神经网络自适应控制器：基于模糊基函数网络的间接型稳定自适应控制器和基于t - s模糊神经网络直接型稳定自适应控制器。
