Description: We present a study of a matrix pencil method for esti-
mating parameters (frequencies and damping factors) of exponentially
damped and/or undamped sinusoids in noise. Comparison of this
method to a polynomial method (SVD-Prony method) shows that the
matrix pencil method and the polynomial method are two special cases
of a matrix prediction approach but the pencil method is more efficient
in computation and less restrictive about signal poles. It is found
through perturbation analysis and simulation that, for signals with un-
known damping factors, the pencil method is less sensitive to noise than
the polynomial method. In Appendix A, a new expression of the Cra-
mer-Ran bound for the exponential signals is presented.-We present a study of a matrix pencil method for esti-

Description: 2D Hetero-Spectral Analysis Conduct 2D hetero-spectral correlation analysis on two matrices (here
SAXS and WAXS data) that contain the same number of points along the
perturbation. This is written for ax3xm matrices where there are a
spectral variables (which are located in column 2) and m points along
the perturbation. Column 3 contains the intensity values. Column 1
contains temperatures (not used here).

Description: 基于子空间方法的联合稀疏恢复，通过MUSIC算法进行结合测试，给出了测试结果-We propose subspace-augmented
MUSIC (SA-MUSIC), which improves on MUSIC such that the
support is reliably recovered under such unfavorable conditions.
Combined with a subspace-based greedy algorithm, known as Orthogonal
Subspace Matching Pursuit, which is also proposed and
analyzed in this paper, SA-MUSIC provides a computationally
efficient algorithm with a performance guarantee. The performance
guarantees are given in terms of a version of the restricted
isometry property. In particular, we also present a non-asymptotic
perturbation analysis of the signal subspace estimation step, which
has been missing in the previous studies of MUSIC. Platform: |

Description: This paper presents the design of an intelligent fuzzy
gain scheduled proportional-integral (FGSPI) controller as the
supplementary controller for load frequency control (LFC) of
two-area interconnected power system with reheat type thermal
unit of equal capacity in each area. The dynamic response has
been studied for 1% step load perturbation in area-1. The
proposed FGSPI controller is compared against conventional
proportional-integral (PI) controller and state feedback linear
quadratic regulator (LQR) controller using settling times,
overshoots and undershoots of the tie-line power and frequency
deviations as performance indices. Comparative analysis
indicates that the proposed intelligent controller gives better
performance than conventional controllers. Platform: |
