The large-scale formation maintenance control of unmanned aerial vehicle based on consensus algorithm and virtual structure was researched. Firstly we develop consensus strategies to guarantee the state formation of the virtual frame in each formation member which may inconsistent. Then, a formation control model based on virtual structure method is adopted to analyze the time-varying trajectory tracking...
A novel algorithm for the similarity search in time series database is proposed. Considering the neural network's poor capability when handling with time change process sequence, the original data is mapped into the feature pattern space by means of discrete cosine transform (DCT) for dimensionality reduction. By analyzing the advantages when the artificial neural network is used as similarity measurement...
