Control of Systems with I/O Delay via Reduction to a One-Block Problem
G. Meinsma, L. Mirkin and Q.-C. Zhong
In this paper the standard (four-block) H_infinty control problem
for systems with a single delay in the feedback loop is studied. A simple
procedure of the reduction of the problem to an equivalent one-block problem
having particularly simple structure is proposed. The one-block problem is
then solved by the J-spectral factorization approach,
resulting in the so-called dead-time compensator (DTC) form of the
controller. The advantages of the proposed procedure are its simplicity,
intuitively clear derivation of the DTC form of the H_infinity
controller, and extensibility to the multiple delay case.
