In this paper, a novel dual-motor driving electric power steering (EPS) system for commercial vehicle is proposed. The parameters matching, system structure, and power-assistance characteristics of this dual-motor EPS system are designed according to a commercial vehicle. The power distribution scheme and fault-tolerant control algorithm are designed. Simulation results show that the power steering...
Based on analyzing the driving system of motors in series, it indicates that the system simplifies the structure and realizes the effective self-action differential when the electric vehicle(EV) runs on the level road without any variety or at low velocity. When the EV runs on the variational road, especially the friction force is variant, the EV is unstable according to the character of the permanent-magnet...
In order to research the anti-slip regulation (ASR) of electric vehicle(EV), this paper analyzes the operating principle and control strategy of electric vehicle's ASR, builds the motion model of the EV and vehicle dynamics model including the tyre, the wheel and the model between the tyre and the road. The traditional ASR structure is complex. In order to solve the problem, a novel anti-slip controller...
There are many uncertainty factors when the electric vehicle (EV) drives in the complicated variable circumstance, it make the control effect of some control modes non-ideal. To ensure the robustness of the closed-loop system under the presence of uncertainties, such as parameter perturbation and unknown model dynamics, and to minimize the effect of disturbances, the mu synthesis robust control is...
