Abstract:

In order to solve the problem that unmanned vehicles are easily influenced by external environmentdisturbances during the process of path tracking, this paper proposes a path tracking method. System simulations andtests are carried out for this method, and it is compared with the effect of traditional linear PID control algorithm.Results show that nonlinear algorithm not only has better dynamic performance, but also can reduce path trackingerror under environmental disturbance and overcome disturbance effectively.
