Genericity of Classes of Observer-Based Compensators
نویسندگان
چکیده
We investigate basic properties of the set of observer-based state-space compensators (OBCs). In particular, we are interested in how much of this set is occupied by its OBC members. We examine both classical OBCs and generalized OBCs, as developed in [D. Cobb, SIAM J. Control Optim., 50 (2012), pp. 1921–1949]. We perform our analysis for both real and complex compensators. In every case, we show that the set of OBCs is not open but has dense interior.

Design of reduced-order multirate output linear functional observer-based compensators
Absmd-Often in controi system design. i t is only necessary to estimate a single (but prespecified) linear function of the system's state for the purpose of implementing a feedback control law. This can be achieved by a linear functional observer which may have order one less than the observability index of the plant. but generically cannot have smaller order. In this paper, we explore the conc...
متن کاملDesign of observer based compensators: The polynomial approach
This paper presents the frequency domain design of observer based compensators related to arbitrary observer orders for state reconstruction in direct equivalence to the well known time domain approach. The parameterization of the state feedback and of the state observer problems are possible without recurrence to the time domain representations of the system, however, the equivalent time domai...
متن کاملSingular Observer-Based Compensators and the Deterministic Separation Principle
The concept of observer-based compensators (OBCs) and the deterministic separation principle have long been cornerstones of modern control theory. In our paper, we extend these ideas via singular system theory to encompass a wider variety of rational compensators. We show that the separation principle generalizes in a natural way to OBCs of all orders, including the static case. We pay particul...

Zusammenfassung In diesem Beitrag wird die beobachterbasierte Zustandsregelung von Strecken mit Stellsignalbegrenzung auf allgemeinere dynamische Ausgangsrückführungen für Zwei-Freiheitsgrade-Regelungen erweitert, die sowohl statische als auch dynamische Rückführungen beliebiger Ordnung umfassen. Die Bestimmung der neuen Ausgangsregler erfolgt durch den unabhängigen Entwurf einer statischen Aus...
متن کاملControl Stability Evaluation of Multiple Distribution Static Compensators based on Optimal Coefficients using Salp Swarm Algorithm
In order to solve the problem of voltage drop and voltage imbalance in the distribution systems, the injection of reactive power by multiple static compensators is used. The distributed generation such as photovoltaic systems could play a role of the static compensators by producing reactive power. In this paper, the integral to droop line algorithm is used to control the reactive power in busb...
