摘　　要：提出了一种旨在改进自适应控制系统性能的模型参考自适应控制新方案,通过引入切换自适应律和静态补偿器,减少系统在自适应调整的初始阶段振荡的幅度和调节时间,提高系统收敛的速度,改善系统跟踪误差的瞬态行为,从而显著地提高系统的鲁棒性和跟踪性能.A new modified model reference adaptive control scheme aimed at improving the transient performance of adaptive systems was proposed in the paper. The switched adaptive law and the statistic compensator in the new scheme eliminate the undesirable phenomena, such as reducing the amplitude of oscillation and regulate time during the initial stages of adaptation, which improve the rate of convergence of trace error and the transient behavior, then robustness and tracking performance are enhanced obviously.
