摘　　要：阐述了发射箱温控系统设计中保温层厚度、冷热负荷、制冷制热量和相应电源功率的计算步骤,提出了一种基于工况和查表的半导体制冷量快速估算方法。给出了系统软硬件设计,运用单向温度控制、温度偏差梯度控制和PID控制等方法,探讨了适用于多传感器和多热泵交错阵列式分布调温系统的控制策略。测试表明系统在控制精度、温度均布性、能耗效率和自动化程度等方面优于已有装备,对延长待机时间和优化箱体内环境控制有积极意义。The procedures of calculating thermal-insulation layer thickness, hot and cold load, semiconductor cooling and heating capacity and corresponding electric power which were involved in designing temperature control system for missile launch canister were analyzed. A rapid method based on working condition and looking-up table for estimating the semiconductor cooling capacity was proposed. The system hardware and software design was also discussed, and a new temperature control strategy for systems with multi temperature sensor and multi heat pumps that were aligned alternately as an array by using unidirectional temperature control, temperature error gradient control, PID control algorithm and other methods was presented. Tests show that the system performance such as control precision, temperature u- niformity, energy efficiency and automation degree, etc. is improved relative to the existing equipment. The result has positive significance for extending the standby time and optimizing the internal environment control of launch canister. The scheme and implementing methods referred in the paper have good reference value for similar designs.
