Abstract：In this paper,a predetermined performance controller is proposed for a modular charging system for electric vehicles to solve the problem of sudden voltage changes caused by changes in the load.Firstly,a barrier Lyapunov function is introduced and combined with the backstepping method to design the controller to ensure that the output voltage of the system can be limited to a set range.Secondly,consider the load changes when the electric vehicle is connected and left,a finite time load estimator is designed to estimate the load variation.A rigorous proof of bounded output voltage and stability is given.Finally,the effectiveness of the designed controller is verified by comparison with conventional PID and finite-time controllers.
