On linear-quadratic dissipative control processes with time-varying coefficients,

with Roberta Fabbri, Russell Johnson and Sylvia Novo,
Discrete Cont. Dyn. Sys. - Ser. A  33 (1) (2013), 193-210.


Yakubovich, Fradkov, Hill and Proskurnikov have used the Yakubovich Frequency Theorem

to prove that a strictly dissipative linear-quadratic control process with periodic coefficients admits

a storage function, and various related results. Their analysis is now extended to the case when the

coefficients are bounded uniformly continuous functions.
