Model reduction based on sparse identification techniques for induction machines: Towards the real time and accuracy-guaranteed simulation of faulty induction machines

چکیده
The development of condition monitoring (CM) systems induction machines (IMs) is essential for the industry because early fault detection would help engineers to optimise maintenance plans. However, use several IMs test and validate diagnosis methods developed requires also costly benches that, anyway, often face limitations in range faults operating conditions be tested. To avoid it, accurate models such as those based on finite element method (FEM) reduce major drawbacks but their inability execute FEM real time largely reduces application on-line continuous systems. alleviate this problem a hybrid FEM-analytical model has been proposed. It uses an analytical that can run real-time hardware loop (HIL) system, after its parameters have computed through simulations. In way, proposed provides high accuracy at cost long simulation times computational costs (both computing power memory resources) compute IM parameters. This work aims reducing these drawbacks. particular, sparse identification techniques balances complexity by selecting number simulations accurately coupling with different severity degrees. Particularly, methodology applied develop abnormal eccentricity levels related mechanical produce most breakdowns.

Matrix analysis techniques in cage induction machines
Modern analysis techniques for electrical machines are either analytical or use finite element analysis. Both methods are implemented using computational techniques to solve the magnetic circuit and produce performance predictions. This paper puts forward a steady-state impedance matrix method for analysing a split-phase induction machine that is at the leading edge of analytical modelling of i...

Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...
متن کاملInduction and State Machines
This short paper describes a well-known and a non-standard technique for proving properties about sequential circuits. The techniques are based on transforming the circuit to an abstract state machine, and performing several ways of induction on these state machines. We conclude with an insightful correspondence between the two techniques. The proposed methods have been implemented in an experi...
