Path-Following Control of Unmanned Vehicles Based on Optimal Preview Time Model Predictive Control

World Electric Vehicle Journal
In order to reduce the lateral error of path-following control of unmanned vehicles under variable curvature paths, we propose a path-following control strategy for unmanned vehicles based on optimal preview time model predictive control (OP-MPC).
