基于MATLAB的自适应PID算法研究

摘要

This paper is to combine adaptive control algorithm with typical PID control algorithms and present an adaptive PID control algorithm.With the help of MATLAB software,different control strategy（typical PID control and adaptive PID control） are researched.From the comparison between typical PID control and adaptive PID control characteristic,the result is got that it manifests the widespread application value of adaptive PID control.%针对常规PID控制和自适应控制的各自特点及基本原理、基本算法,设计出一种新型控制器——基于模型参考自适应PID控制器。并采用MATLAB软件对系统进行仿真。通过对仿真结果的分析可知,该控制器与典型的PID控制器相比,显著提高了系统的动态响应性能指标,系统输出能够很好地跟踪参考模型的输出,具有一定的抗干扰性,鲁棒性较好。
