摘 要: 提出了一種多變量電液伺服系統(tǒng)的解耦控制方法，該方法僅采用輸出、輸入信號(hào)構(gòu)成前饋-反饋復(fù)合解耦控制，能使電液伺服這類線性最小相位系統(tǒng)實(shí)現(xiàn)完全解耦，并且，可配置閉環(huán)系統(tǒng)極點(diǎn)。仿真和實(shí)驗(yàn)結(jié)果表明，該解耦控制策略能獲得滿意的控制效果。

Abstract:A new decoupling control method for mufti-variable electric-hydraulic servo system was pre-make electric-hydraulic servo system which is a nonlinear-minimum phase realize completely decoulping and dis-place poles of the closed-loop system also. The simulation and experiment results have shown that the decoupling control stategy was satisfied.
Key words: electric-hydraulic servo control mufti-variable system decoupling control pole displacement
