Decentralized Multirate Control of Interconnected Systems
نویسندگان
چکیده
The objective of the paper is to present a decentralized control approach to interconnected multirate linear systems with synchronous sampling. Each subsystem is assigned a single sampling rate. It simplifies local controllers design. The overall discrete-time system exponential convergence is achieved at the common sampling period via the concept of the M-matrices. The overall original continuous-time system stability is assured using the stability of the corresponding multi-rate discrete-time system. A numerical example is supplied. The control strategy is natural for plants with widely different characteristic frequencies of subsystems or when sensor measurements are performed at different sampling rates. Key–Words: Decentralized systems, large scale systems, multirate systems, control systems

Decentralized Model Reference Adaptive Control of Large Scale Interconnected Systems with Time-Delays in States and Inputs
This paper investigates the problem of decentralized model reference adaptive control (MRAC) for a class of large scale systems with time varying delays in interconnected terms and state and input delays. The upper bounds of the interconnection terms are considered to be unknown. Time varying delays in the nonlinear interconnection terms are bounded and nonnegative continuous functions and thei...

Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...
