    摘要:

    設(shè)計(jì)了基于比例溢流閥調(diào)壓回路的雙向電液比例張力絞車,，并進(jìn)行了理論分析,。針對(duì)液壓系統(tǒng)的不確定性因素以及卷繞機(jī)構(gòu)參數(shù)變化對(duì)張力控制的影響，提出了直接自適應(yīng)魯棒電液張力控制方法,，并用張力負(fù)載模擬試驗(yàn)系統(tǒng)進(jìn)行了研究,。理論分析與試驗(yàn)均表明,，對(duì)于具有不確定性因素的張力跟蹤控制，所設(shè)計(jì)的電液張力絞車及其控制策略,，具有良好的控制性能,。

    Abstract:

    Based on the pressure regulation circuit using electro-hydraulic proportional relief valve, a bi-directional- electro-hydraulic proportional tension was designed and its theoretical analysis was made. The effect on tension caused by parameter varying and uncertain factors of the hydraulic system was considered, and a direct adaptive robust electro-hydraulic tension control method was proposed. Experimental study was also carried out through a tension load-simulation experimentation system. The theoretical analysis and experimental results show that the proposed electro-hydraulic tension winch and the corresponding control method are effective for the tension control by uncertain factors with satisfying control performance obtained in implementation.
