Continuous robust control strategies in an interception role with variable dynamics

A planar interception problem of a maneuverable target is considered using a linearized kinematic model with constant velocities and first-order dynamics of the interceptor and the target. The controls of the interceptor and the target are bounded. The duration of the interception is prescribed. The interceptor dynamics can vary from one mode to another, while the target dynamics is constant. Using a given linear feedback control and its saturated version, the capture zones are constructed. Numerical examples illustrate that proper change of the interceptor dynamic mode leads to an enlarged capture zone.
