摘要 提出一种基于非光滑Lyapunov函数的Acrobot控制器设计和全局稳定性分析方法.基于三个Lyapunov函数分别设计了三种控制规律,用米增加Acrobot的能量和保持合适的姿态,使Acrobot摇起并稳定在垂直向上的不稳定平衡点.应用LaSalle不变原理和非光滑Lyapunov函数理论,保证了Acrobot在整个运动空间的全局稳定性.仿真结果证明了该方法的有效性. This paper presents a controller design and global stability analysis of acrobots based on non-smooth Lyapunov functions. Three control laws that are derived based on three Lyapunov functions are applied successively to achieve a suitable posture and increase the energy so as to stabilize the acrobot at an unstable inverted equilibrium position. LaSalle invariant theorem and non-smooth Lyapunov function are employed to theoretically guarantee the stability of the acrobot in the whole motion space. Simulation results have demonstrated the validity of this strategy.
