Adaptable method of managing jets and aerosurfaces for aerospace vehicle control

摘要: An actuator selection procedure is presented that uses linear programming to optimally specify bounded aerosurface deflections and jet firings in response differential torque and/or force commands. This method creates a highly adaptable interface vehicle control logic by automatically providing intrinsic decoupling, dynamic reconfiguration, upper bound objective specification, the capability of coordinating hybrid operation with dissimilar actuators. The function minimized algorithm adapted realize several goals, i.e., discourage large deflections, encourage use certain aerosurfaces (speedbrake, body flap) as state, minimize drag, contribute translational control, adjust balance between activity during operation. A model from Space Shuttle aerodynamic data employed simulation examples drive six-axis controller tracking scheduled re-entry trajectory.
