Two approaches are presented in this paper to estimate the state of an induction motor and detect faults: a geometric approach, assuming only that the perturbations belong to known bounded sets with no hypothesis on their distributions inside these sets, and a stochastic approach by Kalman filtering. Recursive and explicit algorithms are presented and(More)

The paper presents an electrical reduced-order model for real-time purposes. This model allows taking easily into account iron losses. Several model extensions for a Kalman filter are defined, in the objective of the thermal monitoring of the induction machine, in real-time. An accurate experimental set-up is presented and machine model identification is(More)
A sensorless control of a high-speed synchronous reluctance motor is proposed in this paper. The control of high-speed motors requires very short sampling periods. Therefore a classical Extended Kalman Filter (EKF) would require an excessive calculation power. To minimize this computational power, an original EKF based on a particular motor model is(More)
In this paper, a robust nonlinear controller for sensorless interior permanent magnet synchronous motors (IPMSM) is designed to track a desired reference which is computed by using a maximum-torque-per-ampere strategy (MTPA). The proposed controller ensures nite-time convergence of sliding variables despite parameter uncertainties and unknown load torque.(More)
This paper highlights the energy errors made for the design of supercapacitors used as a main energy source. First of all, the paper presents the two definitions of capacitance of a capacitance-voltage dependent material. The number of supercapacitors is important for the application purchasing cost. That is why the paper introduces an analytical model and(More)
