中文摘要: |
借助双控制器设计技术和粒子群优化(PSO)算法,提出了一种基于PSO算法的双自由度内模控制方法,即PSO-TDF-IMC,并用于对大时滞工业过程的控制。该方法的基本思想是:以时间乘误差绝对值积分(ITAE)为目标函数,运用PSO算法,优化整定IMC滤波器时间常数。MATLAB仿真结果表明, PSO-TDF-IMC具有算法简单、搜索速度快、效率高等优点,可明显提高双自由度内模控制系统的设定值跟踪性能和鲁棒性能。 |
Abstract: |
With the aid of two controller design technique and particle swarm optimization(PSO) algorithm, a two-degree-of-freedom(TDF) internal model control(IMC) method based on PSO algorithm was proposed, which was suitable for large time delay process. The basic idea of this method was illustrated as follows: taking integral time absolute error(ITAE) as target function, the TDF-IMC filtering time constants were optimized by PSO algorithm. It was indicated by MATLAB simulation results that the proposed TDF-IMC method based on PSO algorithm had such advantages as simplicity for algorithm, fast searching speed and high efficiency, which could improve the setpoint tracking performance and robustness of the TDF-IMC system. |
