System model simulation and control method used in environmental simulation chambers

According to the dynamic state characters of the environmental simulation chamber, a lumped parameter model of temperature and a mathematical model of control system is established to accurately control the temperature of the environmental chamber to measure up to GJB, raise temperature rate and promote control precision. An expert control method is introduced into the design of the temperature control system which is simulated on the platform of MATLAB. By contrast the simulated result with the experimental data, the validation of the lumped parameter model has been proved and the expert control method has been showed with the advantage of no-overshoot, fast response, high precision and great efficiency. The presented methods for the simulation and the control system provide great references to the research on the control laws of other similar problem and show great significance to the relative research field.
