A state space rational controller, with an observer-based structure, is then derived.
The high-level parameters of the rational controller are then fine-tuned using a tuned in closed-loop approach.
We derive reduced-order models for the dynamics in each time scale and outline a rational controller design framework that accounts for this time scale separation.
Similar(57)
In addition, we describe a method to obtain polynomial approximations from above and from below to the value function of the extracted rational controllers, and a method to obtain approximations from below to the optimal value function of the original problem, thereby obtaining a sequence of asymptotically optimal rational controllers with explicit estimates of suboptimality.
Using non-rational controllers we overcome the main difficulty faced when designing rational controllers for linear delay systems, which is to incorporate in the design problem the matrix multiplier used to prove stability with respect to the delayed part of the system.
These approximations are tightenings, rather than relaxations, of the original problem and provide a sequence of rational controllers with value functions associated to these controllers converging (under some technical assumptions) to the value function of the original problem.
This paper addresses the control of linear delay systems using non-rational controllers.
In this paper, criteria for closed-loop identification of an autoregressive, moving average process with exogenous input (ARMAX) regulated with an arbitrary, rational, polynomial controller are derived.
The practical issues to compute fixed-order rational H∞ controllers by convex optimization techniques are discussed.
Furthermore, based on the sum of squares approach, sufficient conditions for the existence of a rational polynomial state feedback controller for a polynomial discrete-time systems are given in terms of solvability of polynomial matrix inequalities.
All stationary experimental conditions corresponding to a discrete-time linear time-invariant causal internally stable closed loop with real rational system and feedback controller are characterized using the Youla Kucera parametrization.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
