In this paper, a new Krein space approach to robust filtering for linear systems with multiple uncertainties is developed. The multiple uncertainties satisfy the energy-type constraints, entering into both state and measurement equations. The proposed approach is used to tackle the sub-optimization problem arising from a sum quadratic constraint (SQC) of system uncertainties. To this end, a novel...
The de-noising effects of wavelet transform, soft threshold, hard threshold and the new threshold wavelet packet were compared by simulation experiments in the paper. It is concluded that the wavelet packet has a good time and frequency domain localization properties and multi-resolution analysis, and the new threshold method can de-noise noisy spectrum effectively, overcome the constant bias and...
Nowadays, cost reduction has become one of the major profit sources for telecom operators, so how to realize profit maximization has always been a focused issue. Given that the customers have different communication demands at busy times and idle times, taking profit maximization as the goal, this paper first establishes a model based on the full load theory in economic to simulate the operation of...
Preknowledge is the foundation of a discipline. First, the definition and construction of preknowledge are given. Fundamental knowledge, relevant disciplines knowledge and special applications knowledge totally three parts compose the preknowledge. Then, according to the characteristics and the development history of simulation science and technology (STT) discipline, the contents of the preknowledge...
