摘要
针对单辙两轮车的不稳定的系统,提出通过控制两个单框架控制力矩陀螺(SGCMG)来研究单辙两轮车的自平衡问题,设计了一个基于滑模控制(SMC)的陀螺角速度控制器,控制SGCMG产生进动力矩,并采用一个奇异回避算法避免陀螺发生奇异现象,以实现整车在静止和动态下的自平衡,并通过仿真验证验证在越障和跨壕沟路况时的自平衡能力.仿真结果表明,所采用的控制方法能够以较小的框架角度使整车快速平衡到直立状态,并且在行驶过过程中很好的抵抗外部干扰,以一个距平衡角度 2°范围内的侧倾角度行驶,仿真结果对单辙两轮车的平衡行驶有显著意义.
Abstract
Aiming at the unstable system of the two-wheel single rut vehicle,a study on the self-balancing problem of a two-wheel single rut vehicle is proposed by controlling two single-gimbal control moment gyro(SGCMG).The two-wheel dynamics model is built.A gyro angular velocity controller based on sliding mode con-trol(SMC)is designed to control the rotation of SGCMG to generate precession torque.A singularity avoidance algorithm is employed to prevent the occurrence of gryocscopic singularities,enabling the self-balancing of the ve-hicle in both stationary and dynamic states.The self-balancing capability is validated through simulation,particu-larly in obstacle and cross-ditch road conditions.The simulation results show that the adopted control method can make vehicle quickly return to upright position with a small frame angle.Furthermore,it exhibits robust resist-ance to external disturbances,allowing the vehicle drive at a roll angle within 2°of the balance angle.The simula-tion results hold significant implications for the balanced locomotion of the two-wheel single rut vehicle.
