Dynamic decoupling control method for PMSM drive with cross-coupling inductances
2017 IEEE Applied Power Electronics Conference and Exposition (APEC), 2017This paper proposes a decoupling control method for high-performance drive of permanent magnet synchronous motors (PMSMs). The conventional decoupling schemes proposed for removing coupling effects on d-q current regulation have the limited performance because the cross-coupling inductances caused by asymmetric structure and saturation are not ...

Induction method of measuring dynamic magnetostriction
Soviet Physics Journal, 1977The method presented in this paper for measuring dynamic magnetostriction gives an idea of the value of the magnetostriction and the shape of its curve as well as its rate of change. It also permits oscillograms to be made of the magnetostriction hysteresis loop as a function of the magnetization field strength and induction.

A dynamic rule-induction method for classification in data mining
Journal of Management Analytics, 2015Rule induction (RI) produces classifiers containing simple yet effective ‘If–Then' rules for decision makers. RI algorithms normally based on PRISM suffer from a few drawbacks mainly related to rule pruning and rule-sharing items (attribute values) in the training data instances.

2013 9th IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives (SDEMPED), 2013
An analytical procedure for computing the inductances of an induction machine in presence of dynamic eccentricity fault is presented. The proposed method is based on the modified winding function approach and takes into consideration harmonics in the winding and the inverse air-gap functions.

A method for dynamic simulation of air-gap eccentricity in induction machines
IEEE Transactions on Industry Applications, 1996In this paper, a method is proposed which enables the simulation of the air-gap eccentricity in induction machines. The method is based on the coupled magnetic circuit approach. The model is derived by means of winding functions, and no symmetry in windings layout is assumed.

Dynamic power on/off method for 3D NoCs with wireless inductive-coupling links
2013 IEEE COOL Chips XVI, 2013Network-on-Chips (NoCs) with wireless inductive coupling have been utilized in real heterogeneous multicore systems. Although the inductive-coupling itself is energy-efficient (e.g., 0.14pJ per bit [1]), inductors continuously consume a certain amount of power, regardless of packet transfers.

Power-Efficient Control of an Induction Motor: Methods of Increasing Its Dynamics
Russian Electrical Engineering, 2019To improve the efficiency of an electric drive system under low speed conditions, a control strategy optimized for maximal torque per ampere (MTPA) is used in the vector control system of an induction motor. MTPA is a control method of motor excitation that significantly reduces the torsion torque dynamics due to the influence of the rotor time ...

A method for dynamic simulation and detection of air-gap eccentricity in induction machines
IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002In this paper a method is proposed which enables the detection of the air-gap eccentricity in induction machines at an early stage. It is shown that by proper modeling of the induction motor it is possible to detect the effect of eccentricity on the machine line currents, whether the machine is running off a sinusoidal supply or a converter. The effect
