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．)

在命令窗口中输入lianxuwuran(t)，回车即可运行，其中t为时间，例如lianxuwuran(20)，表示经过20秒扩散的仿真图像。(Input lianxuwuran (t) in the command window, press Enter to run, where t is time, for example lianxuwuran (20), the proliferation after 20 seconds of simulated images.)

此程序的重点在于用算法完成了OFDM自适应功率分配，做自适应的学友可以参考啊(The focus of this program was completed by algorithm adaptive OFDM power distribution, make adaptive Xueyou can refer to ah)
