摘要
本文将IMC应用于二阶加纯滞后对象,为改善内模控制自适应能力,采用自适应滤波LMS算法对受控对象的模型参数进行在线估计以增强系统的鲁棒性,提高应付时变系统的能力。
IMC(internal model control)method,proposed by Garcia and Morari in 1982, is simple in principle,audio —visual in parameter tuning and easy to imptement.In this paper,internal model control is introduced.In order to improve the system's adaptive ablity,the adaptive filtering method is combined with internal model control to achieve a kind of feasible and easily implement daptive algorithms.
