Because the traditional PID control can not solve the storing coupling among parameters of measurement and control system in double-path thermodynamics test bed. Design a thermodynamics test bed measurement and control system based on expert system. Analyze hardware and software structure of control system, use control method of expert system, simulate expert use knowledge to reasoning and analyze expert control method from pressure transient control, pressure control according to a given curve and the non-perturbation switch of the temperature controller. The test results show that the measurement and control system based on expert control can meet requirement of precision control. The system has passed the check of the experts and been used in operation.
