摘要
针对欠驱动系统TORA,通过部分反馈线性化和全局坐标变换,得到系统的非线性反馈级联模型.为TORA系统提出了一种两步递推反步设计方法,得到系统的非线性控制器.设计过程中利用李雅普诺夫稳定理论保证了系统的稳定性.仿真结果表明系统在任何初始状态下均能渐进稳定于其原点.
The TORA system model is transformed to a feedback cascade model with the partial feedback linearization and a global coordinate change .A two-steps recursive backstepping algorithm is proposed for the TORA system to obtain a nonlinear con-troller .During the design process ,the system stability is guaranteed with the Lyapunov theory .The simulation results show the TO-RA system under any initial states is globally asymptotically stable to its origin .
