具有不完全微分的PID控制方法，可以根据M参数的选择查看演示效果（M=1为不完全微分PID的效果）。(With incomplete derivative PID control method, according to the choice of M parameters to view your presentation (M = 1 is the effect of incomplete differential PID).)

Spatiotemporal rheochaos in nematic hydrodynamics

STK与Matlab的接口及其在复杂航天任务仿真分析中的应用,重点说明STK/Matlab接口的使用 (This guide provides instructions for setting up the interface between MATLAB and STK 10 and its application in complex space mission simulation analysis.)

认知无线电是一种用于提高无线电通信频谱利用率的新的智能技术. 首先简述认知无线电的背景和概念,针 对认知无线电的频谱感知功能,详细地分析基于能量检测的频谱检测方法,在此基础上研究了噪声方差的不确定 性对检测性能的影响. 针对无线信号检测具有本地局域性和能量检测存在信噪比极限的特点,提出一种分布式有 限合作检测机制,推导出基于“OR”规则的有限合作机制的检测概率,并进行Monte Carlo仿真.(Cognitive radio is a radio communications spectrum used to improve the efficiency of the new smart technology. First, the background and outlined the concept of cognitive radio, spectrum sensing for cognitive radio capabilities, a detailed analysis of the spectrum based on energy detection test In this study the noise variance based on the uncertainty of the detection performance. for wireless signal detection with local detection of localized and there is signal to noise ratio limit of the energy characteristics of a distributed cooperative detection mechanism, derived out based on " OR" rules of the detection probability of the limited cooperation mechanism and conduct Monte Carlo simulation.)

滑模变结构仿真，malab源程序。滑模变结构控制算法简单、鲁棒性好和可靠性高，故被广泛应用于运动控制中，尤其被用于可建立精确数学模型的确定性控制系统中(SMVSC simulation, malab source. Sliding mode variable structure control algorithm is simple, good robustness and high reliability, it is widely used in motion control, especially be used to establish a precise mathematical model can be deterministic control system)
