The launcher of a hard-kill type APS (Active Protection System) requires rapid and precise driving to target approaching threats after detection. High angular acceleration is required for rapid driving, which requires high energy consumption. However, the sufficient energy storage of the APS is limited due to weight and space constraints. If energy is insufficient during driving, the charged voltage of the capacitor bank may drop below the minimum operating voltage of the drive motor, which may result in problems such as torque insufficiency or saturation of the controller's integrator. Therefore, it is necessary to determine the maximum angular acceleration possible within the available energy and generate a corresponding driving profile. This paper proposes a method for calculating allowable energy and deriving allowable maximum angular acceleration for driving profile, and validates the proposed method through experiments. We established and implemented a method for deriving maximum angular acceleration through experimental methods to account for unknown frictional forces and mechanical errors in the launcher. By applying the proposed method, we confirmed that the system can operate at high speeds stably by reflecting appropriate angular acceleration even during continuous operation. Therefore, it is expected that the application of the proposed method will improve the operating stability of the APS launcher and enable continuous operation at maximum speed within limited energy.
