An H2 /H∞Robust Control Approach to Electric Vehicle Constant Speed Cruise
Electric vehicle cruise control makes it possible to drive at a desired speed without using the accelerator pedal,which enhances the riding comfort and energy saving.In this paper,electric vehicle cruise control is researched based on an 2 /H H robust control approach.An electric vehicle model is developed firstly combined with application characteristics of electric vehicle cruise control,and is verified according to the datas from actual vehicle.Take the difficulty of acquiring precise vehicle parameters and the influence from road grade to constant speed cruise into consideration,an 2 /HH∞robust control approach of electric vehicle cruise control is proposed.Which not only satisfies the closed loop system stability while the vehicle load changes and some other situations,but also can suppress the influence from road grade effectively.Solve the problem with the approach of linear LMI,we then simulate and verify the control effect in the high precise vehicle dynamic simulation environment with different road circumstances.
