Sensitivity Analysis of Continuous-Time Systems based on Power Spectral Density. (arXiv:1803.10788v1 [cs.SY])

Bode integrals of sensitivity and sensitivity-like functions along with complementary sensitivity and complementary sensitivity-like functions are conventionally used for describing performance limitations of a feedback control system. In this paper, we show that in the case when the disturbance is a wide sense stationary process the (complementary) sensitivity Bode integral and the (complementary) sensitivity-like Bode integral are identical. A lower bound of the continuous-time complementary sensitivity-like Bode integral is also derived and applied to retrieving a control trade-off in a string-like distributed control system.
