Control of single-phase converters connected to the grid via an LCL filter is a demanding issue due to risk of oscillations. A linear-quadratic (LQ) controller enabling besides standard pure sine control also a multi-harmonic current reference is proposed in the paper. Such a design enables to control single-phase converters generating harmonic currents, e.g. shunt active filters, or converters operating...
A new sensorless control algorithm for surface mounted permanent magnet synchronous machines with finite control set model predictive control (FCS-MPC) is proposed and its properties are analyzed. The FCS-MPC usually operates with a short sampling period, therefore the estimation algorithm needs to be computationally cheap. Moreover, injection of high frequency (hf) voltage signals into a given axis...
