Abstract : An improved cost-optimal state feedback control system for stabilizing the inertial reference platform in all-attitude inertial guidance systems which uses the 'region' control concept. It reduces the computational requirements of cost-minimizing state feedback to within the capacity of aerospace vehicle on board control processors. The control system iterates the feedback compensation process so as to reduce the R-gyro error to essentially a zero value and to prevent the gimbal assembly from entering a 'gimbal lock' orientation.
