针对多输入多输出（MIMO）系统，提出了一种新的控制器设计方法-虚拟分组，以处理执行器冗余和故障，扩大可补偿执行器故障集。针对一类非线性MIMO系统，提出了一种自适应补偿方案，以保证系统在未知执行器故障情况下闭环信号有界和输出渐近跟踪。仿真结果表明了自适应设计的有效性。
A new control design technique called virtual grouping is presented to handle actuator redundancy and failures for multiple-input-mutliple-output (MIMO) systems, enlarging the set of compensable actuator failures. An adaptive compensation scheme is thus developed for a class of nonlinear MIMO systems to ensure closed-loop signal boundedness and asymptotic output tracking despite unknown actuator failures. Simulation results are given to show the effectiveness of the adaptive design.
