  • Store separation autopilot
    Patent number: 9964961
    Abstract: A method and apparatus are presented for guiding a store, represented by a dynamic system having transitory nonlinear characteristics, between release from a platform and an activation of a mission autopilot along an optimal path. A nominal reference trajectory is determined that optimizes a desired performance index for the dynamic system using optimal control theory. A feedback control system is implemented that optimizes an original performance index to second order in a presence of disturbances along the optimal path using neighboring optimal control. The feedback control system converges to a linear time invariant regulator approaching the desired operating condition along the optimal path. Finally, control of the store is transitioned to the mission autopilot.
