严格反馈系统的局部最优和全局逆最优全状态反馈设计的最新结果被推广到输出反馈形式的输出反馈系统。在观测输出的导数可用于反馈的假设下，构造了此类系统的动态输出反馈控制律，并在给定的L/sub 2/-增益下实现了局部最优和全局逆最优.当该假设随后下降，控制律实现半全局逆最优性和局部近最优性。
Recent results on locally optimal and globally inverse optimal full-state feedback designs for strict-feedback systems are being extended for output-feedback systems in output-feedback form. The dynamic output-feedback control law for such systems is constructed under the assumption that the derivative of the measured output is available for feedback, and achieves local optimality and global inverse optimality with a prescribed L/sub 2/-gain. When that assumption is subsequently dropped, the control law achieves semi-global inverse optimality and local near-optimality.
