    摘要:

    建立了主/從異構(gòu)式機(jī)器人力反饋遙操作控制系統(tǒng),。主操作系統(tǒng)采用2個(gè)2-DOF操作手,分別采用伺服閥控制液壓馬達(dá)獲得2個(gè)解耦的旋轉(zhuǎn)自由度,。用力信息對(duì)伺服閥進(jìn)行控制以驅(qū)動(dòng)主操作手運(yùn)動(dòng),,解決主手操縱力不能直接驅(qū)動(dòng)主操作手液壓馬達(dá)的問(wèn)題,。從機(jī)器人為4-DOF串聯(lián)關(guān)節(jié)型四自由度機(jī)器人,,采用比例方向閥控制,。分別采用力反射伺服型和力對(duì)稱型雙向伺服控制策略,,對(duì)主/從機(jī)器人系統(tǒng)進(jìn)行遙操作力反饋雙向伺服控制實(shí)驗(yàn)研究,。驗(yàn)證了本設(shè)計(jì)的主操作手結(jié)構(gòu)的合理性,,力對(duì)稱型雙向伺服控制策略具有較好的控制性能。

    Abstract:

    The master-slave force feedback control system of tele-operation was set up. The master manipulator system was composed of two 2-DOF manipulators, and each one adopted two servo valves to control two hydraulic servomotors in order to obtain two rotational decoupling degrees. The master manipulator force information was used to control the servo valve so that the master manipulator could be driven, thus the problem that the master operation force could not directly drive the master manipulator hydraulic motor has been solved. The slave manipulator is 4-DOF system that the original hydraulic shovel bucket was replaced by a new single degree manipulator claw, which set up a series joint 4-DOF manipulator, and hydraulic proportional direction valve control method was applied to the slave manipulator. Force reflection servo and force symmetry bilateral servo control strategies were individually tested on the master-slave system to study the tele-operated force feedback bilateral servo control. The master manipulator’s structure is reasonable, and the force symmetry bilateral servo control method has better control features.
