Error estimates in Second-order Continuous-Time Sigma-Delta modulators
Dilshad Surroop, Pascal Combes, Philippe Martin
Continuous-time Sigma-Delta (CT-) modulators are oversampling Analog-to-Digital converters that may provide higher sampling rates and lower power consumption than their discret…
Sensorless rotor position estimation by PWM-induced signal injection
Dilshad Surroop, Pascal Combes, Philippe Martin +1
We demonstrate how the rotor position of a PWM-controlled PMSM can be recovered from the measured currents, by suitably using the excitation provided by the PWM itself. This provid…
Adding virtual measurements by PWM-induced signal injection
Dilshad Surroop, Pascal Combes, Philippe Martin +1
We show that for PWM-operated devices, it is possible to benefit from signal injection \emph{without an external probing signal}, by suitably using the excitation provided by the P…
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…
Energy-based Modeling of AC Motors
Pascal Combes, Al Kassem Jebai, François Malrait +2
We propose an approach to modeling of AC motors entirely based on analytical mechanics. Symmetry and connection constraints are moreover incorporated in the energy function from wh…
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…
