An Adaptive PID Thermal Control of the Satellite Clock Based on RBF Neural Network

星钟的频率稳定性决定了星钟提供时间信息的精度,而频率稳定性取决于星钟物理核心温度的稳定程度.基于RBF神经网络逼近星钟热模型,设计自适应PID控制方法实现星钟物理核心的温度控制.仿真验证了算法的有效性.

The accuracy of time information provided by satellite clock greatly depends on its frequency stability,which is up to the stability of the core temperature. This paper introduces an adaptive PID control for the satellite clock system whose model is approximated based on RBF neural networks. Simulation results demonstrate the validity of the proposed control.
