JITTERBUG 是一个用来仿真线性控制系统的Matlab工具箱。通过JITTERBUG，我们能得到延时、数据丢失对系统的性能影响。同时，这个工具箱还能计算控制系统中信号的谱密度。(JITTERBUG [Lincoln and Cervin, 2002] is a MATLAB-based toolbox that allows the computation of a quadratic performance criterion for a linear control system under various timing conditions. Using the toolbox, one can easily and quickly assert how sensitive a control system is to delay, jitter, lost samples, etc., without resorting to simulation. The tool is quite general and can also be used to investigate jitter-compensating controllers, aperiodic controllers, and multi-rate controllers. As an additional feature, it is also possible to compute the spectral density of the signals in the control system. The main contribution of the toolbox, which is built on well-known theory (LQG theory and jump linear systems), is to make it easy to apply this type of stochastic analysis to a wide range of problems.)

基于matlab的光伏电池半物理仿真系统的研究 本文从原理上得出简化的光伏电池板数学模型，并分析了在阴影条件下光伏电池板的运行规律，并加以改善，从而得到比较完善的光伏电池板模型。将光伏电池模型在 Matlab/Simulink 中建模并仿真，在 PC机上得出光伏电池 V-I,V-P 特性。最后将 PC 机上 Matlab/Simulink 建立的光伏电池模型通过 AD/DA 板卡于外界真实量交互，为在 Matlab/Simulink 上搭建光伏系统能量提供部分的半物理仿真提出了可行性和合理性。(Research on Photovoltaic Battery Semi-Physical Simulation System Based on Matlab In this paper, a simplified mathematical model of photovoltaic panels is derived in principle, and the operating rules of photovoltaic panels under shadow conditions are analyzed and improved to obtain a more complete photovoltaic panel model. The photovoltaic cell model was modeled and simulated in Matlab/Simulink, and the PV cell V-I, V-P characteristics were obtained on the PC. Finally, the photovoltaic cell model established by Matlab/Simulink on the PC is interacted with the actual amount through the AD/DA board, providing feasibility and rationality for the semi-physical simulation of building photovoltaic system energy on Matlab/Simulink.)

针对滚动轴承故障信号具有非平稳、非高斯的特点，提出了将时域分析与小波分析相结合的方法对滚动轴承进行故障诊断。在研究不同信号分析方法理论的基础上，以滚动轴承外圈故障振动信号为例，采用多种信号处理方法进行了分析。结果表明，各种分析方法在分析轴承故障时的特点各不相同，在实际使用中，可将时域分析与小波分析综合使用，实现轴承状态的实时监测与故障的准确定位。(For rolling bearing fault signals have non-stationary, non-Gaussian, we proposed the time-domain analysis and wavelet analysis method of combining the rolling element bearing fault diagnosis. In the study of different analytical methods based on the theory of signal to the outer ring rolling bearing fault vibration signal, for example, using a variety of signal processing methods are analyzed. The results show that a variety of analytical methods in the analysis of the characteristics of bearing failure vary, in actual use, can be time-domain analysis and synthesis using wavelet analysis, to achieve accurate positioning of the bearing condition monitoring and real-time fault.)
