This work presents an integrated fault detection and fault-tolerant control architecture for spatially-distributed systems described by highly-dissipative systems of nonlinear partial differential equations with actuator faults and sampled measurements. The architecture consists of a family of nonlinear feedback controllers, observer-based fault detection filters that account for the discrete measurement...
This work focuses on control of distributed processes modeled by linear parabolic partial differential equations (PDEs) with constrained and quantized control inputs. Using a suitable finite-dimensional model that captures the PDE's dominant dynamics, we first characterize the inherent conflict in the control design objectives when both control constraints and quantization are simultaneously present,...
This work develops a model-based approach for the detection and compensation of actuator faults in distributed processes described by parabolic PDEs with a limited number of measurements that are sampled at discrete time instances. Using an approximate finite-dimensional system that captures the dominant dynamics of the PDE, an observer based output feedback controller that stabilizes the closed-loop...
This paper presents a model-based networked control approach for managing distributed energy resources (DERs) over communication networks. As a model system, we consider a solid oxide fuel cell (SOFC) plant that communicates with the central controller over a bandwidth-constrained communication network that is shared by several other DERs. The objective is to regulate the power output of the fuel...
This work presents a methodology for the design of a model-based networked control system for spatially distributed processes described by linear parabolic partial differential equations (PDEs) with measurement sensors that transmit their data to the controller/actuators over a bandwidth-limited communication network. The central design objective is to minimize the transfer of information from the...
This work develops a robust fault detection and isolation (FDI) and fault-tolerant control (FTC) structure for distributed processes modeled by nonlinear parabolic PDEs with control constraints, time-varying uncertain variables and a finite number of output measurements with limited accuracy. To facilitate the controller synthesis and fault diagnosis tasks, a finite-dimensional system that approximates...
This paper presents a methodology for the design of integrated robust fault detection and isolation (FDI) and fault-tolerant control (FTC) architecture for transport- reaction processes modeled by nonlinear parabolic partial differential equations (PDEs) with time-varying uncertain variables, actuator constraints and faults.

A model-based fault-tolerant control (FTC) structure integrating nonlinear feedback control, state estimation, fault detection and isolation (FDI), and stability-based actuator reconfiguration is developed for distributed processes modeled by nonlinear parabolic PDEs with control constraints, actuator faults and limited state measurements. The design is based on an appropriate finite-dimensional model...
