摘要The thermal control system (TCS) is a key technology for ensuring good imaging quality of a space optical remote sensor (SORS) in orbit, and its research is of practical significance. In this paper, a multidisciplinary optimization method was proposed for the TCS of a SORS. A particle-swarm-optimized back-propagation neural network was used as the surrogate model to reduce the computational cost of the opto-mechanical-thermal integrated simulation model. Subsequently, the mean and variance of the modulation transfer function (MTF) of 12 fields of view of the SORS at the Nyquist frequency were considered as objective functions, multi-objective optimization of the design parameters of the TCS was performed using the non-dominated sorting genetic algorithm Ⅱ (NSGA-Ⅱ), and the Pareto front composed of a series of Pareto solutions was obtained. A compromise solution was selected as the optimal TCS design. The results showed that, upon comparison with the initial design, the optimal design scheme increased the mean of the MTFs of the SORS by 34.4%, reduced the variance by 31.3%, and significantly improved the comprehensive optical performance of the SORS. © 2023 The Authors
