When nonlinear degree is high , the linear approximation error must be considered 因此在非線性程度較高時,必須考慮減少線性近似誤差。
This class , taught by the guest speaker , is devoted to the study of the approximation error , and some of its general properties 這堂課將由授課的特別來賓講解近似誤差原理及其一般特性。
In order to improve the control performance of the closed - loop system , the adaptive compensation term of the approximation error is introduced 為改善控制系統的性能,引入逼近誤差的自適應補償項。
Simulation results of a duffing forced - oscillation system confirm that the effect of the fuzzy approximation error on the tracking error can be attenuated efficiently by the proposed method 強迫震?系統的模擬結果確定在模糊近似誤差的影響下,追蹤誤差能被有效的衰減。
So a compensator is constructed , which is compensates the approximation error ' s effect on system output at the condition of the approximation error thought as disturbance of the system 所以利用系統跟蹤誤差構造線性最優補償器,該補償器用于減少逼近誤差對系統跟蹤誤差的影響。
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 但是由于模糊系統本身的缺陷,逼近誤差在一定條件下有可能較大,不能忽視,而且這種逼近誤差必然會影響系統的跟蹤誤差。
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 對mamdani系統,分析了隸屬函數分別采用梯形和高斯型時一維模糊系統與函數插值的等價性和逼近誤差。
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 該方法不僅保證了閉環系統的穩定,而且使外部干擾、神經網絡逼近誤差及輸入對輸出的交叉耦合對跟蹤誤差的影響衰減到給定的水平。
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穩定性理論,推導出了神經網絡權值在線學習規律,保證了系統的全局穩定性,同時,為了消除或減小外部干擾以及神經網絡逼近誤差,在控制器設計時結合了魯棒控制方法,使得系統具有一定的魯棒性。
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 該方案利用參考模型作為閉環系統的反饋信號來產生、調節模糊控制器的規則庫,并通過引入最優逼近誤差的自適應補償項來消除建模誤差的影響,不但能保證閉環系統穩定,而且可使跟蹤誤差收斂到零。
