本发明公开了一种基于EMDPSOLSTM的商场中央空调负荷预测方法,系统及介质.该方法包括采集中央空调冷冻水系统的温度,流量数据,以及室外温湿度数据,进行负荷计算;构建LSTM模型并基于EMD分解法进行训练,利用PSO法进行参数寻优;根据历史负荷及室外温湿度数据进行负荷预测.本发明经验模态分解EMD可以将非平稳序列为平稳性序列,降低...
首先通过EMD算法将由惯性导航系统在实时测量得到的船舶运动姿态数据进行分解,得到有限个本征模函数(IMF).然后,利用PSO-LSTM模型学习各IMF分量的短期时序规律并进行预测,将各IMF分量的预测值相加得到最终的预测结果.基于实测数据进行仿真的结果表明,该组合预测模型分别比LSTM模型和PSO-LSTM模型在姿态角的预测中平均绝对...
