Abstract

The invention provides an unmanned aerial vehicle flight state prediction method and system based on LSTM. The method of the invention comprises the following steps: step 1, constructing an action label dictionary; 2, collecting flight state information and motion data of the unmanned aerial vehicle; 3, preprocessing the collected flight state information of each unmanned aerial vehicle; 4, forming a data set in the form of a data matrix; 5, randomly dividing the data set into 70 percent of the training set and 30 percent of the verification set; obtaining the improved LSTM model of a long-short-term memory network with variance by training. 6, tuning the super parameters of the model to obtain a final model by using a verification set; 7: collecting the UAV flight state information of theUAV at the current time which needs to be predicted, and inputting the information into the final model after preprocessing and filtering to obtain the UAV flight motion prediction result. The technical proposal of the invention solves the problem that the existing control model cannot predict the flight action according to the collected flight state data.

Description

technical field [0001] The present invention relates to the technical field of UAV flight control, in particular, to a method and system for predicting the flight state of UAV based on LSTM. Background technique [0002] More than ten years ago, in the early stage of the development of drones, people were more concerned about how to make drones fly stably, faster, and higher. However, with the development of chips, artificial intelligence, and big data technologies, , UAVs have begun to enter the development trend of intelligence, terminalization, and clustering. UAVs have flown from military applications far away from people's vision into ordinary people's homes, allowing laymen to learn for a short time, and can also enjoy stable and reliable flight entertainment. Among them, it is undeniable that the development of flight control technology is the biggest driver of UAV changes in this decade. The flight control of UAVs is one of the main problems in the research field of...
