RSSI算法是指根据无线传感器接受到（目标物体）的信号指示强度，计算该信号在传播中的损耗，根据理论或者经验的信号传播模型将信号强度转换成距离。但是这种算法很容易受到天气，障碍物或人员流动的影响，导致测距不精确，从而定位精度不高。但是由于RSSI算法简单，成本低廉，很多无线通信模块提供RSSI值，所以RSSI算法依然应用在众多领域中。(RSSI algorithm is based on wireless sensor to receive the signal intensity (objects), calculate the signal in the transmission loss, according to the experience of the theory or the signal propagation model will be converted into a distance of signal strength.But this algorithm is very vulnerable to weather, obstacles or the influence of the flow of people, lead to range is not accurate, thus positioning accuracy is not high.But because the RSSI algorithm is simple, low cost, a lot of wireless communication module provides RSSI values, so the RSSI algorithm is used in many fields.)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
