Abstract

In this paper, we propose a backstepping based nonlinear control strategy to ensure the transient performances for the Modular Multilevel Converter (MMC), especially under the emergencies like changing load and operating mode. According to the backstepping control technique, the control input is derived from the Lyapunov stability theory and the established mathematical model. Meanwhile, it can be directly transformed to the desired modulation. After then, combined with the capacitor voltage balancing controller and the circulating current controller, the pulse width modulation (PWM) is triggered correspondingly. The simulative results and the experimental results show that the proposed backstepping control offers many merits over the conventional PI control like settling time and control precision under various conditions.
