说明：  ：针对PID参数复杂烦琐的整定过程这一问题，基于MATLAB／Simulink仿真环境，模拟工程稳 定边界法的PID参数整定策略和步骤，提出了一种简单有效的PID参数整定方法．与通常的整定方法 比较，其优点是非常直观、完全可视化操作、省去了编程的工作量．仿真结果表明该方法具有良好的收 敛性，使得控制系统动态性能得到有效改善，并且很大程度上减少了工作量．(Abstract：The process of PID parameters turning is complicated and time—consuming to engi— neering technician．To solve this problem．simulating the Z～ N method of engineering turn— ing，based on the MATLAB／simulink，a simple and eficient method for PID parameters turning is presented in this paper．Compares with the general methods，it has many advanta— ges，such as simplicity，visual manipulation，leaving out the workload of program and SO on． The simulation results show the effectiveness of this method and be fit for application in the engineering．)

All five matlab file relate to the cluster structure of wireless sensor network. LEACH, BCDCP, ERP, HEED and so on are very helpful to do the simulation.

从初值出发，先计算y对时间t的导数，得到y的变化速度；求出x对t的导数，得到x随时间的变化速度。然后时间前进一小步h=0.002，同时x和y也都发生一个小的变化，即在原来数值基础上加上时间步长h和变化速度的乘积。如果x到达1或者-1，强制让y发生变化。这个过程不断迭代，得到结果。 (completed chart)
