中文摘要
      采用非线性逆系统轨迹控制实现三级倒立摆的自动摆起, 并设计了变增益LQR控制器将其稳定在竖直倒立位置. 首先, 三级倒立摆从静止下垂状态摆起到竖直倒立位置的过程, 从数学角度看是一个两点边值问题, 通过求解该两点边值问题获得摆起的标称轨迹, 利用逆系统方法设计前馈控制, 同时结合增益调度反馈控制使摆起过程稳定; 其次, 在稳定控制阶段, 采用基于逐点线性化的变增益LQR控制器, 实现倒立摆的稳定控制. 仿真实验验证了本方案的有效性.
英文摘要
      The swing-up of the triple inverted pendulum is achieved by inversion-based trajectory control. The variablegain linear quadratic regulator is designed to stabilize the triple inverted pendulum in the upward position. The transient process of swing-up of the triple inverted pendulum is treated as a nonlinear two-point boundary value problem. The normal trajectories of swing-up are obtained by solving a two-point boundary value problem, and a feedforward control is designed by using the inverse system method. A gain-scheduled feedback is used to stabilize the system during the swing-up. In addition, the triple inverted pendulum in the upward position is stabilized by utilizing the variable-gain linear quadratic regulator. Simulation results demonstrate the effectiveness of the proposed control scheme.
