Also it is discussed how to improve loading performance and the actual results using invariance theory . by the feedforward signals of velocity and acceleration, it is expected to expend the bandwidth to 15hz or even higher and reduce the additional torque at 80 percent . in this thesis, i mainly explored the design theory of ehsls and made a lot of experiments on subsystems and the whole system 本文的目的就是設(shè)計、調(diào)試帶有彈簧桿緩沖結(jié)構(gòu)的單通道電液伺服加載臺,通過試驗比較、驗證不同控制算法的工程實際效果;分析和研究應(yīng)用結(jié)構(gòu)不變性原理如何改善加載系統(tǒng)的動態(tài)性能,目的是通過引入速度和加速度的復(fù)合前饋信號將系統(tǒng)的動態(tài)頻帶提高到15hz左右,并且有效的抑制力加載系統(tǒng)固有的多余力矩,抑制比要達到80以上。
The development of aero industry requires high-performance loading system, but now, the bandwidth of the equipment is only 8-10hz . in this thesis an single channel electro-hydraulic servo system is designed to validate . compare and explore different control schemes on restraining additional torque inherent in force loading system 為了滿足飛行器系統(tǒng)仿真的需要,各相關(guān)單位對電液負載仿真臺的性能指標(biāo)提出了很高的要求并提出了各種解決方案,但在滿足雙十指標(biāo)的情況下一般達到的頻帶只有810周。
