Abstract The problem of stochastic speed regulation of the eddy current retarder considering the inaccuracy of the control of the braking torque is researched in this paper. An stochastic speed regulator is designed based on the dynamic model of the eddy current retarder, for the purpose of vehicle speed regulation. The validation of the proposed stochastic regulator is given by the numerical simulation from three folds. Firstly, the simulation results of the road slope is constant value show that the vehicle speed can be regulated to a neighbourhood of its desired value, and the temperature of the rotating disk can be regulated to its equilibrium value. Secondly, the validation of the proposed controller when the road slope is jumped from one degree to other one is given. Finally, the affection of the design parameter to the control performance is discussed, from which we can obtain the relationship between the control performance and the control design parameter.
