将正性理论与标准奇异值鲁棒性检验相结合，建立了连续正真实的控制器设计的鲁棒性。通过将奇异值检验应用于由致动器、计算延迟等引起的偏离正性的模型，即使由于模态不确定性而具有显著的建模误差，也可以确保控制设计的全局稳定性。这一稳定性结果的理论和实验验证。
The robustness of a continuous positive real controller design is established by linking the positivity theory to the standard singular value robustness tests. By application of the singular value test to a model of the deviation from positivity induced by actuators, computational delays, etc., the global stability of the control design can be assured, even with significant modeling errors due to modal uncertainty. Both theoretical and experimental verification of this stability result is presented.
