The problem of global asymptotic tracking by output feedback is studied for a class of nonminimum‐phase nonlinear systems in output feedback form. It is proved that the problem is solvable by an n‐dimensional output feedback controller under the two conditions: (a) the nonminimum‐phase nonlinear system can be rendered minimum‐phase by a virtual output; and (b) the internal dynamics of the nonlinear system driven by a desired signal and its derivatives has a bounded solution trajectory. With the help of a new coordinate transformation, a constructive method is presented for the design of a dynamic output tracking controller. An example is given to validate the proposed output feedback tracking control scheme.

输出反馈形式的非最小相位非线性系统的全局渐近跟踪

针对一类以输出反馈形式存在的非最小相位非线性系统，研究了通过输出反馈进行全局渐近跟踪的问题。证明在两个条件下，该问题可以通过n维输出反馈控制器解决：（a）非最小相位非线性系统可以通过虚拟输出变为最小相位；（b）由所需信号及其导数驱动的非线性系统的内部动力学具有有限的解轨迹。借助于新的坐标转换，提出了一种用于动态输出跟踪控制器设计的构造方法。给出了一个实例来验证所提出的输出反馈跟踪控制方案。
