    摘要:

    無(wú)人駕駛AWID-AWIS車輛是一種全部車輪均可獨(dú)立驅(qū)動(dòng)/制動(dòng),、獨(dú)立轉(zhuǎn)向的先進(jìn)車輛,對(duì)其運(yùn)動(dòng)控制這一基礎(chǔ)問(wèn)題進(jìn)行了研究,。首先建立一種適于無(wú)人駕駛AWID-AWIS車輛的分層式運(yùn)動(dòng)控制體系結(jié)構(gòu),,其上層為運(yùn)動(dòng)控制器,中層為控制分配器,,底層為獨(dú)立車輪伺服控制器,;然后使用擴(kuò)張狀態(tài)觀測(cè)器(ESO)和自抗擾控制(ADRC)方法設(shè)計(jì)車輛運(yùn)動(dòng)學(xué)/動(dòng)力學(xué)集成式運(yùn)動(dòng)控制器;最后開(kāi)展多種工況下的運(yùn)動(dòng)控制仿真,,證明了控制方法的有效性,,指出運(yùn)動(dòng)控制目標(biāo)不能被簡(jiǎn)單地確定。

    Abstract:

    The high performance locomotion control is an essential issue of the unmanned AWID-AWIS (all-wheel-independent-drive & steering) vehicle. Firstly, a kind of hierarchical locomotion control architecture suited to the unmanned vehicle was proposed. Its top layer, middle layer and bottom layer are the locomotion controller, the control allocator and the independent wheel drive-brake-steering servo controller, respectively. Secondly, a novel vehicle dynamic/kinematics integrated locomotion control means was developed using the extended state observer (ESO) and active disturbance rejection control (ADRC) method, and the controller was subsequently designed. Finally, the vehicle locomotion control simulations under different conditions were performed. The results showed the proposed control method is virtual, and that the control objective for AWID-AWIS vehicle locomotion couldn’t be designed simply.
