摘　　要：由于传统PID控制技术较难在非线性、惯性等特性下达到预期的控制效果,因此提出了一种改善传统PID主汽温度控制系统效果的新方法,相比于传统PID方法,该方法采用Matlab软件并结合改进型单纯形寻优法共同整定PID参数。仿真结果表明,在主汽温控制系统中,该方法大量简化了相关寻优过程,且鲁棒性和抗干扰性也较前者更好。The traditional PID control technology is difficult to achieve the desired control effect in nonlinear and in- ertia characteristics. Therefore,this article proposes a new method to improve the control effect of the traditional PID main steam temperature control system,compared with the traditional PID method,it used Matlab software and com- bined with improved simplex optimization method to tune PID parameters. The simulation results show that it greatly simplifies the related optimization process, and its robustness and immunity are also better than the traditional method for the main steam temperature control system.
