This paper considers the problem of optimal L 2 disturbance attenuation with global asymptotic stability for strict feedback nonlinear systems. It is known from previous results that this problem cannot be solved with an arbitrary level of disturbance attenuation (almost disturbance decoupling) if the disturbance input drives unstable zero dynamics of the system. In this case, the problem can only be solved to achieve a level of disturbance attenuation above a nonzero optimal bound. An explicitdoi:10.1109/cdc.2003.1273007 fatcat:ne7ph3t5hfdxljmfyujznxtdte
