| 摘 要： | 研究了比例一微分一积分（PID）控制器参数自整定问题，提出一种基于改进粒子群优化算法的PID控制器参数自整定方法，并以时间乘以误差绝对值积分（ITAE）的性能指标为适应度函数，对具有实参数不确定性的热工对象进行PID控制器参数整定，所设计的PID控制系统的ITAE性能指标比极点法，GPM法，Cohen法，IMC法效果更好，并通过超临界锅炉过热汽温控制的仿真实例验证了方法的有效性。

| Abstract: | This paper studies the self-tuning problem of proportional-integral-derivative(PID)controller.A novel approach based on improved particle swarm optimization(PSO)algorithm is proposed to design the PID parameters.ITAE is an appreciation index for fitness function with good practicability and selectivity.In this paper,thermal objects whose parameters vary in a definite area are considered.The PID control systems tuned by well-known PID tuning methods such as Z-N Optimun,,Cohen,IMC,GPM for thermal models are d... |
