Optimization design of unmanned mining truck path tracking controller based on road adhesion coefficient estimation

Yao Zhang,
Qing Ye,
Jianan Wan
et al.

Abstract: In response to the issues of inaccurate tracking precision caused by continuous turning and variable road adhesion coefficients on complex roads in mining areas for unmanned mining trucks, this paper adopts unscented Kalman filter (UKF) to estimate the road adhesion coefficient. Based on this, an adaptive preview feedforward linear quadratic regulator (LQR) control algorithm is designed using genetic algorithm, feedforward control, and linear quadratic optimal path tracking control methods. Firstly, a nine deg… Show more
