数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

蜂窝小区的程序，是多小区的,讲的比较细致，可以看看(multi-cell easy )

船舶AIS轨迹提取，作出船舶AIS轨迹图。在此基础上，实现基于空间相似距离的K均值轨迹聚类。算法可以自定义轨迹聚类初始轨迹或者由程序随机生成初始轨迹，采用迭代的方法直到确定最终的聚类中心。(The extraction of ship AIS trajectory, make ship AIS trajectories. On this basis, to achieve similar K mean trajectory clustering based on distance space. You can customize the initial trajectory trajectory clustering algorithm or randomly generated by the program initial trajectory, iterative method was used to determine the cluster center until the end. )

说明：  近10年来的大量研究充分肯定了自主神经活动与心血 管疾病死亡率特别是猝死率之间的关系。同时也公认心率变 异(HRV)是判断自主神经活动的最好的定量指标(Nearly 10 years of extensive research activities in full recognition of the autonomic nervous and cardiovascular disease mortality rate in particular, the relationship between sudden death. Heart rate variability also recognized (HRV) is the best judge of autonomic nervous activity quantitative index)
