Abstract

To improve the steering control accuracy and adaptability of robot-driven vehicle(UDRV)under different conditions

a sliding mode control method with particle swarm optimization(PSO)for the steering control of driving robot based on adaptive curve preview is proposed. Firstly

the dynamics models for the test vehicle and the steering manipulator of driving robot are established

then the two models are coupled together to obtain an integrated system dynamics model of the test vehicle manipulated by driving robot. An adaptive curve preview method is proposed

which can make adaptive adjustment for the preview point according to the curvature of the path and the speed of the vehicle. Based on the above

the sliding mode controller with PSO for steering manipulator of driving robot is designed

then the stability analysis is carried out. With the help of PSO

the feedback gain coefficient of the sliding mode controller's switch item is adjusted online to reduce the control chattering. The simulation and test results show that the proposed method can effectively conduct adaptive adjustment according to the path curvature and vehicle speed under different conditions

and the steering control accuracy of UDRV is verified.
