Multirate Digital Decentralized Control Design

چکیده

Multirate digital decentralized control design is presented for linear timeinvariant systems with interaction between subsystems. The design technique, implemented in multirate digital control, eventually allows us to separately design controllers for each subsystem without considering interaction between them. The resulting closed-loop system with interaction between subsystems being eliminated delivers the same desired closed-loop responses each subsystem produces, that can be expected in the design stage. By this we mean that the resulting controller eliminating the interaction between the subsystems delivers desired closed-loop responses in the existence of interaction between subsystems.

Decentralized Multirate Control of Interconnected Systems

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 continu...

On Multirate Digital Redesign of Analog Controllers

In this paper, optimal digital redesign is studied within the framework of sampled-data control theory. In particular, multirate discretization of analog controllers is considered using an H 2 or H 1 optimality criterion. Solutions are obtained via multirate H 2 or H 1 optimization with a causality constraint due to the multirate structure. In two design examples studied , comparison of the pro...

H∞ design of general multirate sampled-data control systems

Direct digital design of general multirate sampled-data systems is considered. To tackle causality constraints, a new and natural framework is proposed using nest operators and nest algebras. Based on this framework explicit solutions to the H1 and H2 multirate control problems are developed in the frequency domain.

Multirate signal reconstruction and filter design via sampled-data control

This paper studies the problem of digital signal reconstruction in the multirate framework. In contrast to the typical digital domain formulation in the current digital signal processing, we present a solution that optimizes an analog performance, via the modern sampled-data control. While the standard technique often indicates that an ideal digital low-pass filter is preferred, we show that th...
