Both hardware architecture and software architecture are discussed. PC/104 embedded computer is used to control equipment for collecting sensor data and sending control commands. PC/104 embedded computer is integrated with A/D, D/A, 8 serial ports card and power supply unit. The surface computer is a X86PC. They transfer data through a fiber line. For software, real-time OS VxWorks is embedded in PC/104. A/D, D/A and serial ports operation are based on VxWorks OS, which increase the real-time quality of control system. Surface computer is the center of motion control and data processing. It is communicated with underwater PC/104 by socket. The whole system has been tested both on land and in tank.展开更多

INTRODUCTIONIt has been known that the theory of topological dynamics has very powerful applications to autonomous as well as to nonautonomous ordinary differential equations. However,so far we have not known any similar works for functional differential equations, essentially in that the state space C([-r, 0], R^n) is not compact.展开更多
