    摘要:

    對異軸兩輪自平衡車(chē)(DATWSBV)進(jìn)行了研究,將其簡(jiǎn)化為具有陀螺效應的倒立擺系統(IPS),采用拉格朗日方程建立非線(xiàn)性數學(xué)模型,并設計了滑模控制器(SMC)和自適應滑模控制器(ASMC)。對無(wú)控制、SMC控制以及ASMC控制的三種模型分別進(jìn)行仿真,結果表明,無(wú)控制的異軸兩輪自平衡車(chē)僅在陀螺儀的作用下無(wú)法恢復直立和完成轉向;相較于SMC,ASMC能使IPS直行受到干擾時(shí)更快地恢復直立,且能達到期望的側傾角以實(shí)現轉向。此外,在BikeSim中建立了DATWSBV的實(shí)車(chē)模型,驗證了此Bikesim模型和IPS數學(xué)模型的一致性,并基于BikeSim和Matlab/Simulink 的聯(lián)合仿真進(jìn)一步驗證了ASMC的控制效果。結果表明,ASMC能夠保證異軸兩輪自平衡車(chē)輛的抗干擾能力和轉向能力。

    Abstract:

    A study was conducted on a two wheel self balancing vehicle with different axles (DATWSBV), which was simplified as an inverted pendulum system (IPS) with gyroscope effect, a nonlinear mathematical model is established using the Lagrange equation, and a sliding mode controller (SMC) and an adaptive sliding mode controller (ASMC) are designed. The three models of uncontrolled, SMC and ASMC controlled were simulated separately, and the results showed that the uncontrolled two-wheel self-balancing vehicle could not restore upright and complete the steering under the action of gyroscope. Compared to SMC, ASMC allows IPS to return to upright faster when disturbed and achieves the desired roll angle for steering. In addition, the actual vehicle model of DATWSBV is established in BikeSim, which verifies the consistency between this Bikesim model and IPS mathematical model, and further verifies the control effect of ASMC based on the joint simulation of BikeSim and Matlab/Simulink. The results show that ASMC can ensure the anti-interference ability and steering ability of heteroaxial two-wheel self-balancing vehicles.
