针对传统空间外热流模拟控制系统功能设计单一,无法快速满足复杂试验要求的问题,设计了一种基于大功率电源的高精度、低成本、多用途外热流模拟控制系统.该系统采用参数自整定PID控制器,通过MATLAB数值仿真和试验调试,验证了系统设计的可行性和可靠性.结果表明:在不同加热结构及工况条件下,控制系统响应速度较快,超调量小,稳定性和鲁棒性好,取得了良好的控制效果.该系统已成功应用于空间热真空环境模拟试验中.
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.
