This paper addresses the problem of accurately estimating the mechanical and magnetic state variables as well as the stator and rotor resistances of induction motors using only the stator current measurements and the supplied stator voltages from an appropriate nonlinear parametrization. The involved estimation is carried out by a high gain adaptive observer designed bearing in mind the available fundamental results together with the useful implementation features, namely conception simplicity and computational efficiency. An exponential convergence of the state and parameter estimation errors is established under admissible assumptions, namely the persistent excitation requirement has been particularly reduced thanks to the introduction of unknown parameter characteristic indices. The effectiveness of the adaptive observer is highlighted throughout simulation results involving a typical induction motor.

“…Two basic approaches to synthesizing observers: a) The heuristic approach close to artificial intelligence (neural network) [20] [21], b) The approach based on the geometry of the machine (introduction of harmonics as functions of the speed of the machine [22] [23]. There are several categories of observers used to avoid difficulties in estimating state variables at low speed such as the extended Kalman filters [22] [24], the extended Luenberger filters [24]; adaptive observers [25]; slippery mode observers [26]; cascade observers and interconnected high gain observers [27] [28].…”

This work proposes an alternative strategy to the use of a speed sensor in the implementation of active and reactive power based model reference adaptive system (PQ-MRAS) estimator in order to calculate the rotor and stator resistances of an induction motor (IM) and the use of these parameters for the detection of inter-turn short circuits (ITSC) faults in the stator of this motor. The rotor and stator resistance estimation part of the IM is performed by the PQ-MRAS method in which the rotor angular velocity is reconstructed from the interconnected high gain observer (IHGO). The ITSC fault detection part is done by the derivation of stator resistance estimated by the PQ-MRAS estimator. In addition to the speed sensorless detection of ITSC faults of the IM, an approach to determine the number of shorted turns based on the difference between the phase current of the healthy and faulty machine is proposed. Simulation results obtained from the MATLAB/Simulink platform have shown that the PQ-MRAS estimator using an interconnected highgain observer gives very similar results to those using the speed sensor. The estimation errors in the cases of speed variation and load torque are almost identical. Variations in stator and rotor resistances influence the performance of the observer and lead to poor estimation of the rotor resistance. The results of ITSC fault detection using IHGO are very similar to the results in the literature using the same diagnostic approach with a speed sensor.

“…As EV is the 0-emission vehicle powered by vehicle battery, many researches of the EV are springing up all around the world, and EV has developed into the small-scale production for business [1][2]. The developments of EV depend on the development of a variety of sciences and techniques, especially for the dynamic performance and driving range improvements, and costs reduction [3][4][5]. In consideration of development cost and time, the establishment of simulation model can contribute to the performance analysis of EV.…”

This paper mainly studies the dynamic matching calculation and main parameter design of the whole vehicle. A practical design scheme for power system of pure electric vehicle is proposed and determined. According to the requirements of dynamic performance, the main parameters of the transmission system are designed and matched by using the knowledge of automobile theory. Through the simulation of the design scheme, the dynamic calculation of the scheme is carried out. The matching analysis of power system of extended-range electric vehicles is carried out in this paper. The power performance of pure electric vehicle is analyzed. In the process of power analysis, the data of maximum speed, gradient and acceleration are mainly analyzed, and the simulation results are analyzed. The simulation results show that the method proposed in this paper is effective and reliable.
