Low temperature heating design and its optimization of low-cost aeroengine controller
To make sure that the low-cost aeroengine controller works stably in low temperature environment,a heating scheme using polyimide heating film was designed.The heating scheme's performance during thermostatic stage and heat-up stage was numerically analyzed and experimentally verified.Simulation results and experiment results show that the heating scheme meets the controller's requirements in temperature preservation and rapid heat-up.In order to improve the temperature uniformity of the components on the main board during heat-up process,an optimization method for heating film's geometry based on genetic algorithm was put forward.Crossover operator and mutation operator was modified according to the restrictions imposed by heating film during practical application:the heating film's layout area should be a connected domain,and the heating film's coverage area should remain constant.The optimization method was applied to the main board's heating film,and numerical analysis was carried out after optimization.Simulation results confirm the effectiveness of the optimization method.
