【摘要】 本论文对智能控制的一个分支——仿人智能控制的算法进行了研究。将仿人智能控制算法与经典的PID调节器以及模糊控制方法相结合,对一个三阶时滞系统进行了仿真控制研究。仿真结果表明,用这种思想设计的控制器改善了单一控制方法的控制性能。 在仔细分析仿人智能控制算法和PID控制器的基础之上,将二者结合,相互取长补短,使其算法与单一的PID控制器比较起来,在快速性、稳定性上有较明显的改善。本文还根据仿人智能控制算法的特点及模糊控制的优势,将其与模糊控制算法相结合,显著地改善了系统的性能,并在此基础上加入动、静态校正的算法,进一步改善了系统的稳定性、快速性,获得令人满意的控制效果。最后,文章通过对仿真结果的分析说明了结合不同控制方式的必要性、合理性。

【Abstract】 In this thesis I do some research on the algorithm of Man-imitating Intelligent Control (MIC), which is one of the promising branches of intelligent control. I introduce the MIC algorithm, classis PID regulator and fuzzy logic, also experiment those methods to a 3-order linear system with time-delay in MATLAB, the simulation results do state those methods improve the control behavior.Based on a thorough analysis of PID controller and MIC algorithm, I combine them together to use their advantages to obtain a better control effect in speediness and stability, compared with simple PID controller. Also, by adding the fuzzy logic to MIC algorithm, I do improve the system performance, further adding dynamic, static adjustment algorithm, I get satisfied control effect especially in stability and speediness. Finally, this thesis presents a conclusion on the simulation results, which interpret the necessity and reasonability of combining different control methods.
