dominant pole no longer is changing as we add more mutuals) at r 0 =4mm, we have a matrix sparsity of 95.02%. Because of the large size of the full dense partial inductance matrix, we are unable to compare the approximation result with the exact solution. However, we will assert correctness of our result in terms of eigen-value pattern of the partial inductance matrix in Fig.6. Fig.6 gives the ...

Our lab has developed a way to measure the contraction of Pneumatic Artificial Muscles (PAMs) using the reinforcing fibers themselves as sensing elements. We achieve this by using electrically-conductive wire to form the fiber braid. The inductance of this “Smart Braid” increases as the actuator contracts. We are interested in using these sensors for the feedback control of fluid systems that r...

In this paper, stator resistance and speed estimation for a vector controlled induction motor drive taking saturation into account is presented. A mathematical dynamic model of an induction motor as influenced by magnetic circuit saturation is presented. Moreover, a modified structure of indirect vector controller scheme is proposed which involves the saturated value of the magnetizing inductan...

In this paper, we present a novel method for statistical inductance extraction and modeling for interconnects considering process variations. The new method, called statHenry, is based on the collocation-based spectral stochastic method where orthogonal polynomials are used to represent the statistical processes. The coefficients of the partial inductance orthogonal polynomial are computed via ...

A cable configuration technique for the balance of current distribution in parallel-connected single-core cables is proposed. Based on the mutual inductance theorem, a closed form solution for the calculation of current distributions in parallel-connected cables is first derived. To compare the performances of different cable configurations, two indices are introduced, one for the power losses ...

Noncalibrated respiratory inductance plethysmography has been used to measure respiratory function by calculation of the phase angle and, more recently, by determination of the ratio of each time to reach peak tidal expiratory flow to total expiratory time (TPEF/TE). Since TPEF/TE is known to be decreased in airway obstruction when derived from flow signals obtained by a pneumotachograph, we wa...

2014 The principles of operation of a modulated inductance magnetometer and the problems that have been encountered in an attempt to realize the expected sensitivity are discussed. A magnetometer for which inductance modulation is effected by a superconducting plane vibrating near a long inductance element is described. The suitability of this magnetometer to the measurement of small magnetic f...

This paper presents a phase-inductance-based position estimation method for interior permanent magnet synchronous motors (IPMSMs). According to the characteristics of phase induction of IPMSMs, the corresponding relationship of the rotor position and the phase inductance is obtained. In order to eliminate the effect of the zero-sequence component of phase inductance and reduce the rotor positio...

The modular toroidal coil (MTC) is composed of several solenoidal coils (SCs) connected in series and distributed in toroidal and symmetrical forms. In this paper, we present an accurate approach for calculation of the mutual and self-inductance between all the SCs of MTC with any arbitrary section. We use Biot-Savart’s and Neumann’s equations to calculate the selfand mutual inductance between ...

This paper introduces an accurate analysis of on-chip inductance effects for distributed interconnects that takes the effect of both the series resistance and the output parasitic capacitance of the driver into account. Using rigorous first principle calculations, accurate expressions for the transfer function of these lines and their time-domain response have been presented for the first time....
