For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum. The surface descriptions of velamen were conducted for D. fimbriatum and D. aurantiacum var. denneanum which are similar in characters of cross section.

The simulation results demonstrate that the controller is valid and effective for synchronous control of the pendulum angle and cart position based on adaptative neuro-fuzzy inference system. And the analogy controllers can be applied to many engineering fields.

仿真结果表明，ANFIS控制器对倒立摆系统的摆杆角度和小车位置的控制过程均具有良好的动态性能和稳态性能，说明了自适应神经模糊推理系统在倒立摆系统控制中的有效性。

It is difficult to control a single inverted pendulum system because of the characteristics of multi-variable, nonlinear and absolutely instability of the system. A controller based on adaptative neuro-fuzzy inference system is designed by using Matlab/Simulink software in the paper. For the sampling data the hybrid algorithm of back propagation algorithm and least squares algorithm is applied in the paper. Thus the parameters of membership function are adjusted and all of the fuzzy rules are generated automatically.

摘 要：针对单级倒立摆系统具有多变量、非线性、绝对不稳定的特点，本文应用Matlab/Simulink 设计了用于倒立摆系统的基于自适应神经模糊推理系统的ANFIS控制器，采用反向传播算法和最小二乘算法的混合算法对倒立摆控制样本数据进行学习，调整各变量的隶属度函数，自动产生模糊规则。
