摘要
考虑一个广义相对阶为 1的多变量系统之变结构模型参考自适应控制器 ( VS- MRAC)设计问题 ,提出了一种切换控制方案 ,解决了现有多变量 VS- MRAC和多变量模型参考自适应控制 ( MRAC)中两个尚未解决的问题 :1 )使系统跟踪误差的每个分量均满足预先给定的性能指标 ;2 )
This paper considers the controller design of a multivariable VS MRAC system of generalized relative degree one. A new switching scheme is proposed which solves the following problems in VS MRAC and MRAC: 1) every component of tracking error can be controlled to guarantee the transient and steady state performance index given by designer in advance, and 2) the usual assumption of positive definiteness property for high frequency gain matrix is not needed.
