摘要: 在模型参考自适应方法的框架上,研究了挠性空间结构的输出反馈鲁棒自适应控制方 法,对其稳定性与动态性能进行了理论分析,该方法通过在标准控制律中增加控制补偿项,利用 挠性结构的特点,将所能容许的乘性模型不确定性的H∞范数提高到接近1的程度,控制系统 的动态性能可由控制器的设计参数调节.对该方法进行了数值实验验证.Abstract: For improving the controller's robustness that is necessary to low-order control, a new output-feedback adaptive control approach for flexible structures is studied. Stability and transient performances of the control system are analyzed. With a term for compensation, the designed controller can tolerate greater multiplicative modeling uncertainty H∞-norm which can be near 1, and transient performance can be improved by alteration of the designed parameters. The presented approach is validated with computer simulation results.
