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 μ synthesis robust control is introduced in this paper, and used in the EV driving control system. The μ 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 μ synthesis robust controllers are superior to the traditional Proportional Integration Differential (PID) controller for reducing steady-state tracking error and accelerating response rate.
