45 1 solution and has low efficiency.
In view of these defects,PSO approaching the target is proposed to better solve the problem of AGV
path planning.When modeling AGV operating environment,the obstacles are transformed into poly-
gons and expanded,and the coordinates are divided by the vertices of the obstacles.The proposed
method introduces the Metropolis criterion to make the algorithm jump out of the stagnant state
quickly.Meanwhile,the adaptive gravity coefficient is proposed to make the algorithm close to the
target and accelerate the convergence speed.The simulation results show that compared with the tra-
ditional algorithm,the PSO approaching the target has certain advantages in the aspects of conver-
gence speed,local optimum and search stability.
