A control system stabilizes a turret having a gimbal and base and pointing a weapon mounted within the turret. The control system includes computer executable modules to receive turret data and operator commands and to modify operator commands in accordance with a generated line of sight vector and ballistic data. The modules include a time optimal controller to generate modified operator commands. The modules further include a gimbal stabilization controller to generate motor commands to stabilize the turret and point the weapon.
