Abstract

In this study, the current tracking problem of PMSM is handled as static feed-forward controller design for Linear Parameter Varying (LPV) system. H infinity controller formulated by means of Linear Matrix inequalities (LMI) with bounded and measurable system parameters is used. Parameter-dependent Lyapunov function is preferred to achieve robust stability against inconstant parameters, throughout the control process. The LPV controller is used in two degrees of freedom (2-DOF), by jointly adding static LPV feed-forward controller on a PI feedback controller. Space vector pulse width modulation (SVPWM) is used to generate switching signals. Overall system is simulated by Matlab/Simulink Software to evaluate the validity of the method in transient and steady state response by computer simulation. Simulation results reveal that proposed method has good dynamic performance and robustness.
