Design and Research of a High Precision External Heat Flow Simulation Control System
Aiming at the problem that the function design of the traditional space external heat flow simulation control system is single and cannot quickly meet the requirements of complex tests,a high-precision,low-cost and multi-purpose external heat flow simulation control system based on high-power power supply was designed.The system uses a parameter self-tuning PID controller.Through MATLAB numerical simulation and test debugging,the feasibility and reliability of the system design are verified.The results show that under different heating structures and operating conditions,the control system has fast response speed,small overshoot,good stability and robustness,and has achieved good control effects.It has been successfully applied in the space thermal vacuum environment simulation experiments.
