“…Automated material handling systems are used widely to transport products in warehouses, or distribute subparts between different assembly stations in a production line [1]. In recent years, vehicle electric power-assisted steering system and its control strategy have been researched both at home and abroad, and some intelligent algorithms have been applied to vehicle electric powerassisted steering system, including neural network, fuzzy control, H∞ control, LQR, road feel feedback, and optimization algorithm, etc [2][3][4][5][6][7]. Most of the research achievements mentioned above aimed at passenger cars, but forklifts have unique working properties as a kind of industrial trucks.…”
