The aim of this paper is to study the performance of a simplified indirect field oriented control algorithm suited for small power induction actuators. The main particularities of the control strategy under study are the use of a disturbance observer in the speed and position control loops, and...

The aim of this paper is to propose a modification in the classical indirect field oriented control strategy to reduce its sensitivity to electrical parameter uncertainties. This modification is based on a theoretical sensitivity analysis and introduces in the control strategy a very simple...

The contribution of this paper is to provide a simple but quite rigorous analytical method for computing the cogging torque in surface mounted permanent magnet synchronous machines. It relies on the fact that the magnetic energy variation due to the presence of a slot on the stator side of the...

Polyphase permanent magnet synchronous motors are well suited for electromechanical actuation systems demanding a high level of reliability. They are indeed able to run on a reduced number of phases and therefore to make the actuation system fault tolerant. The paper introduces a Lagrangian...
