摘要

In this study, the development of an improved output feedback controller for the positive output (P/O) super-lift re-lift Luo converter is presented. The main feature of the proposed controller is that despite the non-minimum phase obstacle presented by the boost-type dc-dc converter, the output voltage is regulated directly. Moreover, the structure of the proposed controller is such that it is insensitive to the load variations and there is no risk of saturation in the control law due to division by zero. The stability analysis of the closed-loop controlled system is provided and the feasibility of the proposed controller is shown. The feasibility analysis shows that the 'remaining dynamics' for the controlled converter has only one equilibrium point which is always stable. Finally, some simulations as well as experimental results are also provided to illustrate the features of the proposed feedback control strategy.
