9414345 Jayasuriya In this research project, a frequency domain design methodology is developed for the synthesis of controllers for highly uncertain systems to insure robust stability, for assuring non- overshooting step responses and other time-domain specifications, and for maximizing the tolerance to external disturbances. In addition, a new control theory is formulated for eliminating critical speed vibrations and other rotodynamic instabilities in high speed rotors by utilizing actively controlled magnetic bearings. The control methodology is applicable to multivariable uncertain plants with more actuators than controlled out puts and to linear time-varying and nonlinear compensation for the elimination of limitations brought about by the presence of non- minimum phase zeros. ***

在本研究项目中，开发了一种频域设计方法，用于高度不确定系统的控制器综合，以确保鲁棒稳定性，确保非超调阶跃响应和其他时域规格，并最大化对外部干扰的容忍度。此外，制定了新的控制理论，以消除临界速度振动和其他旋转动力学不稳定的高速转子利用主动控制磁轴承。该控制方法适用于执行器多于控制输出的多变量不确定对象，并适用于线性时变和非线性补偿，以消除非最小相位零的存在所带来的限制。* * *
