Adaptive Nonlinear States Observer Design of Switched Reluctance Machine
Authors: , , , , ,
Abstract: This paper presents an adaptive nonlinear observer designed for switched reluctance machines (SRMs). In this study, a diffeomorphism transformation was performed to reformulate the system into an observable form, and then a Kalman high-gain observer (KHGO) was developed to online estimate the electrical and mechanical parameters of the machine. The performance of the observer is confirmed through simulations carried out using MATLAB/Simulink environment under various scenarios. The results confirmed its ability to accurately estimate the electromechanical states of the machine, for different operating conditions.
