Abstract :
This paper presents a flatness based method to control a non-ideal DC/DC boost converter. An online trajectory planning algorithm is used to control the total energy stored in the system. The trajectory is planed thanks to polynomial form which is valid on a finite horizon. This method is applied at first to an ideal DC/DC boost converter. Then, an online estimator is used to track the evolution of the converter losses and the load variations and therefore, a more realistic model is developed for a non-ideal converter. The applied control strategy is finally adapted to the completed converter model. Therefore, a high dynamic nonlinear control is deduced for a non-ideal DC/DC boost converter. The experimental results prove validity of the control method and the system losses estimator.
