【摘要】：基于單端口網(wǎng)絡(luò)的無源性理論,建立機器人吸附足與葉片壁面的端口網(wǎng)絡(luò)系統(tǒng),給出觸力柔順控制所需的無源性條件;設(shè)計無源觀測器能量觀測算法,無源控制器根據(jù)系統(tǒng)能量變化預(yù)測值和觸力反饋值,修正吸附足位置。在Matlab/Simulink中的Sim Mechanics搭建的三自由度爬壁機器人仿真測試平臺和實物樣機測試平臺上開展無源性控制實驗。仿真和樣機實驗結(jié)果一致表明,所設(shè)計的算法可將觸力控制在穩(wěn)定吸附閾值和沖擊閾值內(nèi),實現(xiàn)足壁觸力的無源柔順。
[Abstract]:Based on the passive theory of single-port network, the port network system of robot adsorbing foot and blade wall is established, and the passive condition for the control of touch force compliance is given. The passive observer energy observation algorithm is designed. The passive controller modifies the position of the adsorption foot according to the predicted energy change and the contact feedback value of the system. The passive control experiment is carried out on the simulation test platform of three-degree-of-freedom wall-climbing robot and the test platform of physical prototype built by Sim Mechanics in Matlab/Simulink. The results of simulation and prototype experiments show that the proposed algorithm can control the contact force within the stable adsorption threshold and impact threshold to achieve passive compliance of foot contact force.
