Control of stable delayed systems using algebraic tools and the modified Nyquist criterion
Original language description
The main objective of the proposed contribution is to demonstrate a modern control approach based on algebraic means when control stable processes with time delay not only in input-output relation but also with internal (feedback) delays. The methodologydescribed in this paper, unlike many other methods, does not require any time delay approximation. A control structure combining the simple feedback control structure with a control system with two degrees of freedom is considered. The control design isperformed in the special ring of stable and proper retarded quasipolynomial (RQ) meromorphic functions via the solution of the Bézout identity with Youla-Kučera parameterization. It is also claimed that the procedure is not unique. Final controllers areof so-called anisochronic type and ensure feedback loop stability, tracking of the step reference and load disturbance attenuation. The modified Nyquist criterion pertaining to the chosen control system structure is a starting-point of a
