This paper discusses multi-objective controller synthesis for the fuzzy T-S (Takagi-Sugeno) model. Various performance specifications are included. Both the state-feedback controller and the dynamic feedback controller are presented. They are in the format of a PDC (parallel distributed compensation) controller which is essentially a nonlinear controller. The controller synthesis is formulated ...

We study the optimal distributed control (ODC) problem and propose a design method based on the approximation of the H2 performance using the optimal centralized controller. The designed distributed controller obeys a prescribed sparsity pattern in the frequency domain. The proposed method enables a convex approximation of the distributed controller problem, which has a closed-form solution wit...

Progress toward the implementation of distributed engine control in an aerospace application may be accelerated through the development of a hardware-in-the-loop (HIL) system for testing new control architectures and hardware outside of a physical test cell environment. One component required in an HIL simulation system is a high-fidelity model of the control platform: sensors, actuators, and t...

We study a multi-agent output regulation problem, where not all agents have access to the exosystem’s dynamics. We propose a distributed controller that solves the problem for linear, heterogeneous, and uncertain agent dynamics as well as time-varying directed networks. The distributed controller consists of two parts: (1) an exosystem generator that creates a local copy of the exosystem dynami...

This paper considers the design of feedback controllers for linear, time-invariant, spatially distributed systems in an approach which generalises the H∞-framework and in particular the H∞ loop-shaping method. To this end, we introduce a class of spatially distributed system models called /nite dimensional, distributed, linear, time-invariant systems. Sensors and actuators are considered to be ...

This article investigates a formation control problem of mobile robots. Two main issues of the formation control problem are addressed; one is the implementation of distributed formation control and another is the analysis of effect of network communication on the closed-loop systems. The distributed formation control is obtained by modelling the formation control problem as a linear-quadratic ...

Controller design strategy for Takagi-Sugeno (T-S) fuzzy systems is considered in the two-degree-of-freedom (TDOF) framework. Firstly, coprime factorization described in the state space formulas for T-S fuzzy systems is introduced based on a common Lyapunov function. Secondly, based on this coprime factorization, TDOF framework for LTI systems is extended to be applied to T-S fuzzy systems. Con...

This article introduces a novel distributed controller approach for networked control systems (NCS) to achieve finite gain L2 stability independent of constant time delay. The distributed controller is alternatively interpreted as a linear transformation of the inputoutput space of the controller and the plant, and in fact represents a generalization of the well-known scattering transformation....

Centralized control algorithm limits the hardware flexibility of a modular multilevel converter (MMC). Therefore, distributed structure has recently started to be seen in industry application. Even though controller reduces single point failure risk compared centralized controller, entire systems increases due number local controllers. However, can programmed such way as replace faulty and sust...
