摘　　要：基于九点控制算法的基本原理,针对超辐射发光二极管光源温度控制模型出现的控制对象具有高阶次、大滞后、强耦合、非线性及参数时变的特性,难以利用有效的解析式数学模型进行控制,提出采用九点控制算法实现超辐射发光二极管光源温度控制系统的设计。利用Simulink对该设计方案进行了仿真分析,仿真结果表明:与传统PID控制相比,该控制方案具有调节时间短、响应速度快、控制稳定和控制精度高的特点,对下一步光源的数字化实现具有重要指导意义。Based on the basic principle of nine-point control algorithm,the author put forward the design of Super-luminescent diode system in which nine point control algorithm is adopted.The design offers a solution which is targeted at the closed-loop control by analysis mathematical model is not efficiently achievable,because of the fact that the object to be Controller are characterized by their high order,big lagging,close-coupling,non-linear and time-varying parameters.Simulating and analyzing this scheme by using Simulink,the simulation results indicate that appling this controller to power amplfier,this scheme can significantly hance the stability and reliability,it has control stability and high control accuracy characteristics,it is important to the digitization realization in the future.
