Protecting the power grid: strategies against distributed controller compromise
… elements for monitoring and control. Distributed controllers play a prominent role in deploying this cohesive execution and are ubiquitous in the grid. As global information is shared and acted upon, faster response to system changes is achieved. However, failure or malfunction of a …

A Distributed Digital Control Architecture for Power Electronics Systems
… design that is based on the open-architecture distributed digital controller and modular power electronics building blocks (PEBBs). The proposed distributed digital controller partitions the controller in three levels of control authority. The power stage controller, designated as hardware …

Synchronization of classes of dynamical networks : analysis and control
… of a network is studied by introducing a distributed controller as well as a more flexible switching distributed controller. The total control effort of the controller is constrained by a cost function. First, parameters of the constrained distributed controller which can synchronize the …

Multiple Robot Boundary Tracking with Phase and Workload Balancing
… cooperative multiple robot system as applied to distributed tracking and sampling of a boundary edge. Within this system the boundary edge is partitioned into subsegments, each allocated to a particular robot such that workload is balanced across the robots. Also, to minimize the time between …

CONSENSUS OF MULTI-AGENT SYSTEM FOR AGENTS WITH UNSTABLE LINEAR DYNAMICS
… the use of a diagonal gain matrix in a dynamic controller setting. The main contributions are: necessary and sufficient conditions for consensus for fixed networks and networks switching among undirected and connected graphs, and sufficient conditions for consensus for networks switching among …

Controller synthesis for reactive systems in distributed, real-time and hybrid settings
We investigate controller synthesis in distributed, real-time and hybrid settings. In distributed setting, we prove that the monadic second order theory of the event structure unfolding of every system of connectedly communicating processes (CCP) is decidable. With this, we show that the …

Rapid prototyping of rapid prototyping machines
… is developed which treats the machine as a distributed Internet Zero network controlled by a software virtual machine with the benefits of simplified configuration and greater flexibility. A low cost circuit board milling machine, built as the test bed for this distributed controller, is …

Modeling and control of high density microcantilever systems
… arrays and present simple state feedback controllers that can achieve reasonable performance. These controllers are localized, spatially distributed and yield tracking performances comparable to the performance of the more complex H infinity controller that takes disturbances and couplings …

The design of decentralised controllers for large scale systems
… include fewer tuning parameters than centralised controllers, the simplification and cost reduction of hardware requirements and greater reliability. In addition the application of decentralised controller design to large scale systems allows established CAD methods to be implemented easily and …

Dynamic Locomotion and Whole-Body Control for Compliant Humanoids
… We develop low-level, mid-level, and high-level controllers to enable low-impedance balancing and walking on compliant and uneven terrain. For low-level control, we present a cascaded joint impedance controller for series elastic humanoids with parallel actuation. A distributed controller …

Gradient-Based Distributed Model Predictive Control
… model predictive control (MPC) and particularly distributed model predictive control (DMPC). One topic of the thesis is gradient-based optimization algorithms for solving the optimization problem arising in DMPC in a distributed manner. The underlying idea is to solve the optimization problem in …
