In this paper, a nonlinear controller is proposed for a three-phase rectifier so that its input current does not exceed a given limit. At the same time, the proposed controller can achieve accurate dc output voltage regulation and reactive power control independently from system parameters including the load during the normal operation. Using the generic $dq$ transformation and the nonlinear model...
In this work, a non-linear controller with an inherent current-limiting property is proposed to achieve dc output voltage regulation and unity power factor operation for single-phase ac/dc converters. The proposed current-limiting non-linear controller (CLNC) acts independently from the system parameters and is proven to guarantee closed-loop system stability using non-linear control theory. Without...
When paralleled inverters feed a common load, it is required that the load is shared according to their power ratings. In this paper, the robust droop controller (RDC) proposed in the literature for achieving accurate proportional power sharing for paralleled inverters is implemented in a way to ensure a bounded closed-loop performance. Using non-linear Lyapunov methods, it is shown that the controller...
