    摘要:

    無人駕駛AWID-AWIS車輛是一種全部車輪均可獨立驅動/制動、獨立轉向的先進車輛,對其運動控制這一基礎問題進行了研究。首先建立一種適于無人駕駛AWID-AWIS車輛的分層式運動控制體系結構,其上層為運動控制器,中層為控制分配器,底層為獨立車輪伺服控制器;然后使用擴張狀態(tài)觀測器(ESO)和自抗擾控制(ADRC)方法設計車輛運動學/動力學集成式運動控制器;最后開展多種工況下的運動控制仿真,證明了控制方法的有效性,指出運動控制目標不能被簡單地確定。

    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.
