摘要
针对模型参考自适应控制对延迟鲁棒性较差的问题,提出了将动态特性接近被控对象的参考模型作为前馈补偿器,从而改进系统性能的补偿方法。仿真结果表明,该补偿方法效果明显,且对不确定的延迟扰动有一定的鲁棒性。
The model reference adaptive control has poor robustness for time delay, in this paper a feedforward compensator that established by reference model whose dynamics is approaching to the plant dynamics is placed to recover the system performance. Simulation results show that this method is effective, and robust to uncertain time delay perturbation.
