Optimal robust state-feedback controllers that minimize tracking errors over all times t ≥ 0 are considered. It is shown that such controllers exist for nonlinear input-affine systems that satisfy a certain controllability condition. Easy-to-implem

The problem of maintaining low operating errors during feedback outages is considered for a class of nonlinear systems with time-delays in the input channel. It is shown that there are optimal controllers that keep operating errors below a specified
