Modeling Electrical Motor Dynamics using Encoder-Decoder with Recurrent Skip Connection
Sagar Verma, Nicolas Henwood, Marc Castella +2
Electrical motors are the most important source of mechanical energy in the industrial world. Their modeling traditionally relies on a physics-based approach, which aims at taking…
Obtaining the Current-Flux Relations of the Saturated PMSM by Signal Injection
Pascal Combes, François Malrait, Philippe Martin +1
This paper proposes a method based on signal injection to obtain the saturated current-flux relations of a PMSM from locked-rotor experiments. With respect to the classical method…
An analysis of the benefits of signal injection for low-speed sensorless control of induction motors
Pascal Combes, François Malrait, Philippe Martin +1
We analyze why low-speed sensorless control of the IM is intrinsically difficult, and what is gained by signal injection. The explanation relies on the control-theoretic concept of…
Adding virtual measurements by signal injection
Pascal Combes, Al Kassem Jebai, François Malrait +2
We propose a method to "create" a new measurement output by exciting the system with a high-frequency oscillation. This new "virtual" measurement may be useful to facilitate the de…
Energy-based modeling of electric motors
Al Kassem Jebai, Pascal Combes, François Malrait +2
We propose a new approach to model electrical machines based on energy considerations and construction symmetries of the motor. We detail the approach on the Permanent-Magnet Synch…
Sensorless position estimation of Permanent-Magnet Synchronous Motors using a saturation model
Al Kassem Jebai, Francois Malrait, Philippe Martin +1
Sensorless control of Permanent-Magnet Synchronous Motors (PMSM) at low velocity remains a challenging task. A now well-established method consists in injecting a high-frequency si…
Signal injection and averaging for position estimation of Permanent-Magnet Synchronous Motors
Al Kassem Jebai, François Malrait, Philippe Martin +1
Sensorless control of Permanent-Magnet Synchronous Motors at low velocity remains a challenging task. A now well-established method consists in injecting a high-frequency signal an…
Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model
AlKassem Jebai, Francois Malrait, Philippe Martin +1
We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an ene…
Euler-Lagrange models with complex currents of three-phase electrical machines and observability issues
Duro Basic, Francois Malrait, Pierre Rouchon
A new Lagrangian formulation with complex currents is developed and yields a direct and simple method for modeling three-phase permanent-magnet and induction machines. The Lagrangi…
