When nonlinear degree is high , the linear approximation error must be considered 因此在非線(xiàn)性程度較高時(shí),必須考慮減少線(xiàn)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(lái)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(tǒng)的性能,引入逼近誤差的自適應(yīng)補(bǔ)償項(xiàng)。
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(qiáng)迫震?系統(tǒng)的模擬結(jié)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(tǒng)跟蹤誤差構(gòu)造線(xiàn)性最優(yōu)補(bǔ)償器,該補(bǔ)償器用于減少逼近誤差對(duì)系統(tǒng)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(tǒng)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(huì)影響系統(tǒng)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(duì)mamdani系統(tǒng),分析了隸屬函數(shù)分別采用梯形和高斯型時(shí)一維模糊系統(tǒng)與函數(shù)插值的等價(jià)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(huán)系統(tǒng)的穩(wěn)定,而且使外部干擾、神經(jīng)網(wǎng)絡(luò)逼近誤差及輸入對(duì)輸出的交叉耦合對(duì)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(wěn)定性理論,推導(dǎo)出了神經(jīng)網(wǎng)絡(luò)權(quán)值在線(xiàn)學(xué)習(xí)規(guī)律,保證了系統(tǒng)的全局穩(wěn)定性,同時(shí),為了消除或減小外部干擾以及神經(jīng)網(wǎng)絡(luò)逼近誤差,在控制器設(shè)計(jì)時(shí)結(jié)合了魯棒控制方法,使得系統(tǒng)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(huán)系統(tǒng)的反饋信號(hào)來(lái)產(chǎn)生、調(diào)節(jié)模糊控制器的規(guī)則庫(kù),并通過(guò)引入最優(yōu)逼近誤差的自適應(yīng)補(bǔ)償項(xiàng)來(lái)消除建模誤差的影響,不但能保證閉環(huán)系統(tǒng)穩(wěn)定,而且可使跟蹤誤差收斂到零。
