An Optimal Current Observer for Predictive Current Controlled Buck DC-DC Converters

Sensors, 2014
In digital current mode controlled DC-DC converters, conventional current sensors might not provide isolation at a minimized price, power loss and size. Therefore, a current observer which can be realized based on the digital circuit itself, is a possible substitute.

Current Dynamically Predicting Control of PMSM Targeting the Current Vectors

Journal of Electrical Engineering and Technology, 2015
This paper present a current predicting control method for PMSM (permanent magnet synchronous motor) to improve the tracking performance of stator current, which regards the current vector as the control target. Solving the model state equation in the static frame (α-β frame), the dynamic change of current vector will be gained as three independent ...

Model predictive control and sliding mode control for current sharing in microgrids

2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
This paper deals with the design of a hierarchical control scheme for complex islanded Alternate Current (AC) microgrids. The proposed solution relies on the combined use of Model Predictive Control (MPC) and Sliding Mode Control (SMC). The model of the microgrid includes several Distributed Generation Units (DGus), affected by unknown load dynamics ...
