“…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.…”

Abstract-Enhancing the safety of forklift power-assisted steering system is a problem urgently to be solved in practice. First of all, forklift power-assisted steering system model is established according to Lagrange dynamical equations, and three variable assistance characteristics curve fitted for reach trucks is designed combined with fuzzy control algorithm. Then sliding mode variable-structure control method based on motor current control is used tracking the target current and making contrast with the traditional PID in order to justify the validity of the algorithm. Finally, the expression of speed with tri-function is built. Optimization of safety speed is added on the basis of traditional power-assisted steering to ensure the stability and security of forklift steering.
