Guaranteed Margins for LQG Regulators
ity of the desired transfer-function matrix T,(s) is that the matrix equation (9) is consistent for m > 3 m (i.e., for the case where there are more equations than unknowns). However, as it is seen below, this condition is not sufficient. Suppose that it is required to test the admissibility of a desired transfer-function matrix TAs). Also consider another transfer-function matrix Tu@), for whi...
متن کاملRobust H2 Performance: Guaranteeing Margins for LQG Regulators
This paper shows that H 2 (LQG) performance speciications can be combined with struc-tured uncertainty in the system, yielding robustness analysis conditions of the same nature and computational complexity as the corresponding conditions for H 1 performance. These conditions are convex feasibility tests in terms of Linear Matrix Inequalities, and can be proven to be necessary and suucient under...
متن کاملGuaranteed Performance Control for Discrete-time Lqg Problems
Guaranteed performance control is considered in this paper for discretetime LQG problems by minimizing the probability that the performance index is over a preselected threshold. It is proven that this guaranteed performance control problem can be converted into a mean-variance control problem which can be solved by using an embedding scheme. An optimal open-loop feedback control law is derived...
متن کاملGuaranteed Cost LQG Control of Uncertain Linear Quantum Stochastic Systems
In this paper, we formulate and solve a guaranteed cost control problem for a class of uncertain linear stochastic quantum systems. For these quantum systems, a connection with an associated classical (non-quantum) system is first established. Using this connection, the desired guaranteed cost results are established. The theory presented is illustrated using an example from quantum optics.
متن کاملSemideenite Programming Techniques for Reduced Order Systems with Guaranteed Stability Margins: a Numerical Study
In this paper, the compensator based reduced order control design framework of 2] is modiied to yield low order systems with guaranteed stability margins. This result is achieved through use of a logarithmic barrier function. In addition, a reduced basis method is formulated in which the compensator equations are approximated on uneven grids; guaranteed stability margins are also included. The ...
