| 摘 要： | 针对高精度直流伺服系统,提出一种基于Lyapunov直接法的鲁棒模型参考自适应控制方法.在算法中,通过调节增益系数,以适应系统中参数的变化,通过引入鲁棒补偿项,实现对摩擦环节的补偿,使得在具有参数不确定性和未知非线性摩擦特性的情况下,跟踪误差渐进收敛于零.并以三轴转台为例,进行了数值仿真,其结果表明该方法的有效性和鲁棒性.

| Abstract: | A robust model reference adaptive control algorithm based on Lyapunov' direct method is presented for high precision DC servo system. By tuning of the gain coefficients and robust term, the algorithm is able to maintain robustness under parametric uncertainty and compensate for unknown friction. Lyapunov's direct method is used to prove the global convergence of the tracking error in the presence of parametric uncertainty and unknown friction. Computer simulation applied to a high precision flight simulator demonstrates the effectiveness and robustness of the proposed algorithm. |
