Identification of nonlinear time varying system using feedforward neural networks 利用前饋神經(jīng)網(wǎng)絡(luò)的非線性時變系統(tǒng)的辯識
Variable structure robust controller for linear time varying systems with disturbances 帶有干擾的線性時變系統(tǒng)變結(jié)構(gòu)魯棒控制器
In addition , morse proved that tenable system must be a minimum phase system . for linear time varying systems , tskalis and loannou ( 1992 , 1989 ) proposed mrac design method 為了保證可調(diào)性,被控對象必須是最小相位的,對于線性時變系統(tǒng), tskalis與ioannou 992 , 1989 )給出了模型參考自適應(yīng)控制器的設(shè)計方法
In this dissertation , a kind of linear time invariant systems with unmodeled dynamics and nonlinear uncertainties are considered by using backstepping approach and variable structure control algorithm . also another kind of linear time varying systems are studied based on the same method 本文主要利用backstepping方法與變結(jié)構(gòu)控制方法,研究了有未建模動態(tài)及不確定非線性項的線性時不變系統(tǒng),以及輸入通道帶有干擾的線性時變系統(tǒng)的控制器設(shè)計問題
Using the cogent validity of backstepping " s solving parametric - strict - feedback nonlinear systems , xinghuo yu and wu yuqiang ( 1998 ) solved the output - tracking problem of a kind of linear time varying system by combining nonlinear damping method and variable structure scheme . in this dissertation , we sufficiently consider the effect of disturbances in the input channel basing on the same model Xinghuoyu和yuqiangwu ( 1998 )針對一類線性時變系統(tǒng)的輸出跟蹤問題,基于back飛tepping設(shè)計機制,將帶有非線性dallpipg項的設(shè)計方法與變結(jié)構(gòu)控制方法相結(jié)合,給出了一種新的非線性控制器設(shè)計方法
