This letter investigates the problem of output tracking control subject to transient and steady-state performance constraints for unknown pure-feedback systems. On the basis of monotonicity theory, we ...

This note addresses the existence and implementation of the infinite-horizon controller for the case of active steady-state input constraints. This case is important because, in many practical ...

A federal appeals court late Thursday paused a ruling that required President Donald Trump to return control of members of California’s National Guard to the state.
