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…
