| 英文摘要 |
| In this paper, a trajectory tracking control method for sanitation vehicles based on model-free adaptive iterative
learning is proposed considering the problems of model time-varying and unknown disturbance aiming the periodic
repetitive work characteristics. First of all, the kinematics model of two-wheeled mobile robot is built for the sanitation
vehicle. Secondly, a full-format dynamic linearized data model with time-varying parameters and nonlinear uncertainties
in the iterative domain is presented. Then a model-free adaptive iterative learning control (MFAILC) algorithm with time
difference estimation algorithm for trajectory tracking based on the optimal performance index is designed. At the end, the
simulation analysis was carried out. The research results show that the body angle of the trajectory tracking system of the
sanitation vehicle decreases with the increase of iteration. Compared with the traditional iterative learning control algorithm,
the improved method has slack conditional constraints and better robustness, and the control accuracy is improved. |
