Predictive Converter Control: Hidden Convexity and Real-Time Quadratically Constrained Optimization

This brief considers model predictive control of voltage source converters with null null null LCnull null null 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 and nonconvex. An in-depth analysis reveals a convex structure of the converter model, and a nonlinear variable transformation is introduced, which allows to...
