摘要
以法国的兆焦激光装置LMJ的Echelle 1冷冻靶原型为基础,对冷冻靶的末端传热机构进行建模及干扰分析,提出了一种基于实时检测的多变量温度控制系统设计方案。对传热机构各部件进行多点温度实时检测以提高测量精度,并且能够针对不同的控制目标切换控制策略。利用Matlab/Simulink对"缓慢冷却"和"快速冷却"两种降温方法进行仿真,结果表明,系统的动态响应性能及稳态精度均满足了不同降温阶段的具体要求。
Thermal model and disturbance analysis of the cryogenic arm of LMJ＇ s prototype ＂Echelle 1＂ have been studied. A control system based on synchronous detection and ＂multi-variable＂ algorithm has been proposed in order to perform a high resolution regulation of the cryogenic target temperature. This system performs multipoint syn- chronous temperature detection to improve measurement accuracy, and switches control schemes according to different control objectives. Simulations of both ＂Slow Cooling＂ and ＂Quick Cooling＂ methods were carried out using Matlab/ Simulink. The results show that both the dynamic and the static characteristics of the control system can satisfy specif- ic requirements of different cooling phases.
