摘要:
针对交流电机伺服控制系统,提出一种多变量自寻优稳态解耦模糊控制器。控制器回避多变量模糊规则库的构建问题,由前后两级串联而成,前级为常规单变量模糊控制器的简单并联,后级为解耦系数矩阵。为了限定控制器的基本应用范围,以闭环控制系统的多项式矩阵描述为基础,给出线性定常系统渐近稳定的基本必要条件。利用被控对象的稳态增益矩阵,在稳定状态附近实现系统的解耦控制,并引入额外的解耦系数评估调节子模糊控制器,对其进行实时评估和调节,进一步改善系统的动态性能。理论分析和仿真验证了控制方案的正确性和有效性。
Abstract:
In order to accelerate fuzzy control theory application in AC machine servo system,a novel multivariable self-optimizing steady-state-decomposition fuzzy control structure with two series-connected stages was put forward.The first stage consisted of simply parallel-connected conventional univariable fuzzy controllers and the second one was a numerical decomposition matrix.Such kind of decentralized structure skillfully avoided the painstaking task of multivariable fuzzy rule base construction.Based on the P...
