| 摘 要： | 为了解决大滞后系统控制难度大的问题，针对非线性、大时变、大延迟的控制对象，设计一种带嵌入式函数的最优PID参数自整定控制方法，通过仿真实验与ISTTE最优准则下最优PID参数自整定控制方法进行了比较，给出仿真波形及其分析，通过仿真实验结果表明该控制方法不仅具有PID控制器高精度、稳定性、鲁棒性高的优点，另外可以缩短系统的调节时间，有效地抑制系统的超调，从而可以有效改善大滞后系统的控制效果。

| Abstract: | In order to solve the difficulty control problem of big lagging systems, an optimal PID parameter self-adjusting control method with embedded function is designed. The control method aims at the systems with nonlinear, large timevarying and time delay. The improved control method is compared with the optimal PID parameter self-adjusting control methods which conforms to ISTTE optimal standard by a simulation experiment. The simulation wave patterns and analysis are given. The experiment results indicate that the improved control method possess a lot of advantages such as the properties of high-accuracy, high-stability and high-robust. The control method can shorten the sdjusting time of the system and restrain overshoot effectively, and improve the control effect of the big lagging system. |
