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 introduced in this paper, and used in the EV driving control system. The mu synthesis robust controller for driving of EV is designed, ensuring the robustness, performances - such as response speed and steady-state error - when there is perturbation of EV voltage of the battery and the driving mode. The experimental results with different voltage of battery and driving modes show that the mu synthesis robust controllers are superior to the traditional Proportional Integration Differential (PID) controller for reducing steady-state tracking error and accelerating response rate.
