基于局部化技术的多模型自适应控制
LOCALIZATION BASED MULTI-MODEL ADAPTIVE CONTROL
【摘要】 对一类含跳变参数的单输入单输出离散时间被控对象 ,建立由多固定模型和自适应模型组成的多模型 ,并通过引入指标切换函数构成多模型自适应极点配置控制器 ,在保证闭环系统稳定的前提下 ,改善系统瞬态响应 .同时采用局部化 (Localization)技术优化多模型模型集 ,在不损失计算精度的前提下 ,大大减少了计算量 ,提高了计算速度 .
【Abstract】 Multiple fixed models and adaptive models are set up to cover the uncertainty of a SISO discrete time system with unknown and jumping parameters, and a multi model adaptive pole assignment controller is proposed by using a switching index function. On the premise that closed loop stability is guaranteed, this kind of multi model adaptive control (MMAC) can improve the transient response greatly. At the same time, localization method is introduced to reduce the computation burden of multi model algorithm without loss of accuracy.
