针对众所周知的非线性基准系统RTAC（旋转平移作动器），解决了输出反馈全局跟踪问题，其中一个未测量状态以二次形式出现在状态方程中。我们的观测器-控制器反推设计产生了一个非线性输出反馈控制器，该控制器强制平移位移全局渐进地跟踪适当的时变信号。所提出的解决方案是新的，即使在全局输出反馈稳定化的情况下，即当参考信号为零。
The output-feedback global tracking problem is solved for the well-known nonlinear benchmark RTAC (rotational-translational actuator) system, where one of the unmeasured states appears quadratically in the state equations. Our observer-controller backstepping design yields a nonlinear output-feedback controller that forces the translational displacement to globally asymptotically track an appropriate time-varying signal. The proposed solution is new even for the case of global output-feedback stabilization, namely when the reference signal is zero.
