The robust adaptive leader-follower formation control of uncertain unmanned surface vehicles (USVs) subject to stochastic environmental loads is investigated in this paper.The stochastic additive noises are included in the CALCIUM kinematics which stands for the un-modeled dynamics and uncertainty.The disturbances induced by waves, wind and ocean c
In view of problem of data information lost and low prediction accuracy caused by common descending dimension methods for gas HERBATINT 7M monitoring data in gas emission prediction, high dimensional sample data is transformed into one-dimensional projection data by combining principle of projection pursuit with differential evolution algorithm, an
