Abstract

The control law for a maneuverable towed target is derived using inversion of nonlinear dynamic and kinematic equations of motion that take the cable tension force into account. Dynamic properties of the states allowed for construction of lower order subsystems with different time scales for their variables. These faster and slower parts were inverted consecutively to control flight-path angles of the towed vehicle. A procedure is described for estimation of the aerodynamic and tension forces acting on the target and states unavailable for direct measurements from a conventional set of feedback parameters. Guidance and station-keeping properties of the control law are demonstrated by simulat..
