Leader-follower formation control is a widely used distributed control strategy that requires systems to exchange their information over a wireless radio communication network to attain and maintain formations. These wireless networks are often subject to deep fades, where a severe drop in the quality of the communication link occurs. Such deep fades inevitably inject a great deal of stochastic uncertainties...
An interconnected wireless networked system consists of numerous coupled subsystems that need to exchange information over wireless communication channels. The use of these wireless networks induces a great deal of stochastic uncertainty that often results from deep fades, where a severe drop in the quality of communication link occurs. Such uncertainty negatively impacts the system's performance...
Model-based fault detection methods have the potential to reduce the size, weight, and cost of safety-critical aerospace systems. One obstacle to the application of these methods is a lack of appropriate tools to efficiently certify their reliability. This paper focuses on the false alarm analysis of a general fault detection scheme. The main difficulty of the false alarm analysis is the time-correlations...
A resilient control system is one that maintains state awareness and an accepted level of operational normalcy in response to unexpected disturbances. There has recently been great interest in event-triggered control for networked systems. It is unclear, however, whether event-triggering is appropriate for resilient control because of the sporadic nature of the feedback. This paper examines the bit-rates...
A 160 × 120 bolometer uncooled infrared read out circuit (ROIC) and detector equivalent model were presented. The SPICE simulation model was based on the relationship between micro-bolometer material thermal parameters and electrical parameters. Blind pixel compensation technique was used in the ROIC to suppress self-heating effect. As the main part of the ROIC, capacitive transimpedance amplifier...
The posture control of micro quadrotor is the key point in flying stability, in this paper, the structure of quadrotor is analyzed, and the kinetic equation has been deduced, a new proportional-integral-derivative controller (PID) control algorithm has been set up based on the velocity matrix, the parameters are simplified and divide to eight classification due to the value of the error. The simulation...
The various applications of polarimetric SAR data have brought to the fore questions of polarimetric calibration. Most polarimetric calibration methods based on distributed targets employed reflection symmetry assumption, which might be inconsistent with the truth due to a possible orientation angle shift, and therefore would skew the polarimetric signatures of targets. In this paper, a model incorporating...
In this paper, the cryptographic properties of the Plateaued functions such as propagation criterion, linear structures are studied by a new method, which is denoted by the dot product matrix. The upper and lower bounds of the correlation coefficient when the element is not in the linear structures set are presented. The count of the nonzero correlation coefficient set of the Plateaued functions on...
The project-based organizations engaging in engineering consultancy are at the early stage in China. For the manager of China, how to conduct the organization design for them according to contextuality that characterizes the conditions of China is an important issue. First, the factors that affect the performance of this type of the project-based organization of China are analyzed. Then, the organizational...
A three-dimensional implementation of the lumped-networks by Crank-Nicolson finite-difference time-domain (CN-FDTD) algorithm has been presented in this paper. The resulting difference equations allow an arbitrary two-terminal network to be inserted into one FDTD cell, preserving the full explicit nature of the conventional FDTD scheme and requiring a minimum number of additional storage variables...
