Abstract

A linear active disturbance rejection control (LADRC) strategy for permanent magnet synchronous motor (PMSM) for road-sensing based on the differential evolution (DE) algorithm is proposed in this paper, called DE-LADRC, to obtain the better dynamic and steady-state responses of the road-sensing simulation in electric vehicle (EV) steering-by-wire (SBW) systems. Since the novel control method ignores the time delay modules in digital motor control, the controlled object is regarded as a first-order inertial link to design a first-order LADRC controller. Then aiming to solve the problem where the values of the controller parameters are changed and difficult to tune due to ignoring the time delay modules in the first-order LADRC controller, the differential evolution (DE) algorithm is designed to find the optimal controller parameters by selftuning. Experiment results indicate the effectiveness and convergence of the DE-LADRC, as well as the correctness of the road-sensing planning. In addition, the DE-LADRC can provide the smoother feel and real-time road-sensing for driver due to experiment of a Hardware in the Loop (HIL) platform under convergent iteration.
