This thesis attempts to offer a possible improvement for conventional anti-submarine system which is mounted on warship. It consists of two parts: the control law and its realization concerning the particular problem. The control based on optimal theory is devised for three-dimentional minimum-time interception. A microprocessor system is also designed to achieve all necessary steps to track and attack the target. The thesis focuses on the question of how to launch a group of subcharges to destroy a submarine cruising under water: find the optimal trajectory by developing a numerical method to solve the nonlinear dynamic system and design a Mc68000 microprocessor system to coordinate all necessary steps.

Some examples under this optimal control are illustrated. They include open-loop, unbounded control and closed-loop, bounded control. The hardware and software for this system are also discussed. The project shows that minimum-time control is physically reasonable and valid for submarine interception.
