Abstract:

The trajectory tracking control of unmanned vehicle with a sequence of human-like behavior primitives as the desired trajectory is studied.A trajectory tracking control method combining the offline optimization of behavior primitives and the online coordination of game is proposed.Based on the behavior primitive library extracted directly from real driving data,a model-based nonlinear optimization method is applied to generate a behavior primitive library that satisfies the constraints of vehicle kinematic properties.The optimal control parameters for each category of primitives in the behavior primitive library are obtained by offline optimization using the particle swarm algorithm,and a multilayer perceptual machine is applied to establish the mapping relationship between the optimal parameters of controller and the categories of behavioral primitives.Based on the optimization of the control parameters within the primitives,the online game coordinated control method is used as the core to generate the optimal control parameter between the behavior primitives.The experimental results show that the proposed trajectory tracking control method can significantly improve the tracking accuracy of the behavior primitive sequences and effectively solve the problem of stable and smooth transition between independent behavior primitives.
