Abstract

This paper presents an innovative control law for permanent magnet synchronous motor (PMSM) drive for high dynamics applications. This kind of system (three-phase inverter connected with a PMSM) exhibits nonlinear behavior. Classically, to control the speed and the current (torque), a linearized technique is often used to study the stability and to select the controller parameters at specific operating point. In this paper, a model based control based on the flatness property of the drive system is proposed. Flatness provides a convenient framework for meeting a number of performance specifications on the PMSM drive. To validate the proposed method, a prototype PMSM drive (1 kW, 3000 rpm) is realized in the laboratory. The proposed control law is implemented by digital estimation in a dSPACE 1104 controller card. Experimental results demonstrate that the nonlinear differential flatness-based control provides improved speed/current regulation relative to a classical linear PI vector control method.
