ABSTRACT: The problem of controlling the chaotic permanent magnet synchronous motor (PMSM) is addressed. Based on the Lyapunov stability theory, a state feedback controller is designed to make the system states track desired references even when the system exhibits chaotic behavior. Both cases of certain and uncertain systems are considered. System performances are maintained in spite of parametric uncertainties. Numerical simulations are then presented to show the effectiveness of the proposed controller
