| Abstract: | A microcomputer system for physiological low pressure chamber control was developed. Its lifting velocity, retention altitude, fresh air flow, temperature and humidity are controlled by decoupling and PID algorithm. And the system possesses the functions of alarm, parameter display and print, history curve display of controlled variables and real-time modification by keyboard. The results of testing show that the control accuracy is satisfactory. The mechanism of chamber lifting and its natures at low altitude are also analysed. |
