This brief considers model predictive control of voltage source converters with $LC$ filter. The converter model describes the nonlinear effect of the switching on the converter state, and the model predictive control (MPC) problem is thus nonlinear

This paper considers the operation of a load commutated inverter (LCI) fed synchronous machine when the stator voltage is too low to ensure commutation of the machine side thyristors. Under such low-voltage conditions, the LCI is operated in a so-cal

The paper considers the optimal choice of gains of proportional-resonant controllers applied to control voltage source inverters. An inverter, controlled in closed loop, but without proportional resonant controllers, is modeled as a second order tran

This paper considers model predictive control (MPC) of switched mode power converters and uses a hybrid prediction model that represents the switching ripple of the converter state. The goal of the approach is to achieve both high dynamic performance

The paper considers control of a three phase three level grid-tied voltage source inverter with LCL filter based on optimal pulse patterns and model predictive control. The model predictive approach requires a non-convex optimization problem to be so

Model predictive control schemes for power electronic applications are characterized by a great variety of problem formulations. In this paper, we consider a three phase voltage source converter with an arbitrary number of voltage levels and derive a

This paper considers model predictive control of a class of piecewise affine systems and introduces a method to reduce the complexity of the optimisation problem which is solved online. The optimisation problem is a mixed-integer quadratic program wh
