approximation error meaning in English
逼近误差
近拟误差
近似误差
Examples
- Since the fuzzy descriptions are imprecise and may be insufficient to achieve the desired accuracy , it is necessary to design a compensator to removing the influence of the approximation error
但是由于模糊系统本身的缺陷，逼近误差在一定条件下有可能较大，不能忽视，而且这种逼近误差必然会影响系统的跟踪误差。 - The equivalence between the mamdani type fuzzy systems using trapezoid or gauss membership functions and the piecewise interpolation functions is demonstrated . and the estimation of the approximation error is given
对mamdani系统，分析了隶属函数分别采用梯形和高斯型时一维模糊系统与函数插值的等价性和逼近误差。 - It is shown that the proposed scheme guarantees the stability of the closed - loop system and achieves tracking performance idex , meanwhile the influences of external disturbance , neural network approximation error and the cross - coupling of input to output on the tracking error are reduced to a prescribed level
该方法不仅保证了闭环系统的稳定，而且使外部干扰、神经网络逼近误差及输入对输出的交叉耦合对跟踪误差的影响衰减到给定的水平。 - The proposed approach overcome the disadvantages which the neural network need learning off - line before using as a controller and lack of real - time and can not guarantee stability of the system , hi order to eliminate the extern disturbance and approximation error of network , the controller design combine with robust control approach and the system possess robustness
基于lyapunov稳定性理论，推导出了神经网络权值在线学习规律，保证了系统的全局稳定性，同时，为了消除或减小外部干扰以及神经网络逼近误差，在控制器设计时结合了鲁棒控制方法，使得系统具有一定的鲁棒性。 - The mrafc scheme employs a reference model to provide closed - loop performance feedback for generating or modifying a fuzzy controller ' s knowledge base . the adaptive compensation term of optimal approximation error is adopted . by theoretical analysis , the closed - loop fuzzy control system is proved to be globally stable , with tracking error converging to zero
该方案利用参考模型作为闭环系统的反馈信号来产生、调节模糊控制器的规则库，并通过引入最优逼近误差的自适应补偿项来消除建模误差的影响，不但能保证闭环系统稳定，而且可使跟踪误差收敛到零。
