摘　　要：运用分散模型参考自适应控制方法研究了一类不确定时滞大系统问题.在选择参考模型时,根据系统所期望的性能指标,考虑各子系统的相互作用,保留了互联项.这类不确定大系统的关联及干扰是时变不确定的.在这种不确定性界存在但却未知的情形下,基于Lyapunov稳定性理论,给出了其分散自适应控制律,并证明了整个互联大系统是一致最终有界的.A class of uncertain time-delay large-scale systems is studied by using decentralized model reference adaptive control where the reference model was selected according to the performance which the system expected,with the interaction between subsystems taken into account so as to keep the interconnected terms.The interconnections and disturbances in such uncertain large-scale systems are time-varying and uncertain.Under the conditions that the bounds of uncertainties are unknown though they come into being,the decentralized adaptive control law is given and it is proved that an entirely large-scale interconnected system is ultimately uniformly bounded by Lyapunov stability theory.
