Abstract: Considering the issues of depleted shutdown guidance of solid carrier, a depleted shutdown guidance method based on zero-effort interception state is proposed. In the closed-loop guidance stage, considering the gravitational acceleration difference of the target and carry, a display-guided method based on zero-effort interception state is deduced. It is a simple, high guidance precision, versatility guidance method. In the energy management stage, the energy management strategy is designed to apply to the zero-effort interception state. It reduces the severe jitter in the end of energy management and also ensures the carry is on the zero-effort interception state. The simulation shows that the depleted shutdown guidance method ensures the shutdown time is above zero-effort interception state and high-precision hitting the target.
