【Abstract】 In this paper, a dual-control system for adustingtemperature and vacuity based on PC bus industry computer isintroduced to achieve optimum control for the vacuity gaspressure, the temperature and the polytechnic parameters. Thissystem adopts a dual-mode algoritlun, which consistS ofBang-Bang and PID adjusting, to make up and ensure a proPerionitriding atmosphere, to adjust the temperatUre outputaccrding to a given glow current and to adjust the gaspressure according to the exteffial voltage.更多还原
