Abstract

For unstable linear systems with actuator magnitude constraints, we present a method for designing smooth feedback control laws which yield maximal regions of attraction. The designed feedback control law produces a closed-loop region of attraction identical to the open-loop region of asymptotic null-controllability. We apply the result to the problem of stabilizing a statically unstable aircraft in the longitudinal direction
