一阶加纯滞后对象的PID控制器参数整定方法的比较研究

摘要

在工业控制领域，以一阶加纯滞后控制过程为研究对象，分别采用Z-N法、粒子群、模糊控制对PID控制器的参数进行整定，并且从稳定性、跟踪性、以及抗干扰性等方面通过MATLAB仿真，分析比较各自的优缺点。研究结果表明粒子群算法以及模糊控制法对于PID参数的整定在综合性能方面有一定的优势，并对现代工业控制的PID整定设计方面有一定实用价值。%In the ifeld of industrial control,to a ifrst order plus dead time control process for the study,were used Z-N method,PSO,fuzzy control parameters were tuning PID control ers,and from stability,tracking,as wel as other aspects of immunity by MATLAB simulation,analysis and comparison of their advantages and disadvantages.The results show that particle swarm optimization and fuzzy PID control method for the whole parameter set in terms of overal performance has certain advantages and tuning PID control of modern industrial design has some practical value.
