The Temperature Control Based on Internal Model Used for Structure Strength Thermal Experiment

According to simulate aerodynamic thermal characteristic in the flying process of aero craft, structural strength thermal experiment test the aero craft thermal performance on the ground. The experiment validity depends on the given target temperature spectrum tracking ability. This paper presents one temperature spectrum tracking method based on internal model control, in order to improve the performance of structural strength thermal experiment. The control value is given by the internal model controller and system estimation model. By changing the parameter of feedback filter, the overshoot in the tracking process can be suppressed. The experimental simulation analysis shows that the proposed method is effective and feasible.
