Firstly , while the nominal model is used , the filtering effect is very good . secondly , when the system model is n ' t definite , the filtered heading angle and rudder angle are steady in the error range . finally , when the complicated nonlinear wave model replaces the linear wave model , the filtering effect is also steady , and the estimate precision is high 首先,仿真是在名義模型的情況下進(jìn)行的,此時(shí)h _濾波器的濾波效果很好;其次,我們?cè)谙到y(tǒng)模型具有攝動(dòng)的情況下進(jìn)行仿真,此時(shí)經(jīng)h _濾波器濾波后的航向輸出和舵令輸出基本能夠達(dá)到穩(wěn)定;最后,我們采用較復(fù)雜的非線性海浪模型代替線性海浪模型進(jìn)行仿真, h _濾波器的濾波效果也是比較穩(wěn)定的,并且估計(jì)精度較高。
