Evaluation of Multiple Controller Software Defined Networks
… and transmission delays. In larger networks, single controller architecture will be inefficient to manage the network. To tackle this issue, Software Defined Architecture with multiple controllers has been introduced in the recent research. Multiple controller SDN architectures will be …

Signal Control for Partial Cloverleaf Interchanges
… two closely spaced intersections controlled by a single controller at partial cloverleaf interchanges. A case study was provided to demonstrate the feasibility of implementing a single controller at two closely spaced T-intersections that are commonly seen at a partial cloverleaf interchange. A …

Self-Tuning Methods for Multiple-Controller Systems
… parameters and multiple decision-makers or controllers each having his own objective is considered. Based on a centralized information pattern, steady-state solutions are obtained for the stochastic adaptive Nash game and Leader-Follower game problems. These adaptive solutions, after a …

Analysis and IC Implement of Digitally Controlled Multi-Port DC -Dc Converters
… system analysis, (2) design of IC-based digital controller, and (3) implementation and testing of the design. As for digital control system analysis, a time-invariant modeling concept is introduced by including switching frequency and sampling frequency. In digital controller design, two most …

Supporting Transparent Distributed Messaging for Dataflow Applications in Power Electronics Control Systems
… where configuration is the number of controllers used in the system plus the processor allocation strategy used. It also enables an automated processor allocation strategy to transparently configure an application for any number of processor nodes without requiring any changes or …

Multi-Phase Smart Converter for PV System
… a multi-phase smart converter with single controller is proposed as a low cost panel-level MPPT solution. This proposal can largely reduce cost by saving MPPT controllers, current and voltage sensors without sacrificing energy production. The effectiveness of the proposal has been …

The role of the regulator, auditor and banker: the limits of regulation
… Act 2000 (FSMA 2000) or the operations of the single controller and regulator, the Financial Services Authority. This work compares the Bank of England's and the Financial Services Authority's regimes to argue that: The supervision of banks and credit institutions is necessary for ensuring a …

Investigation of a hybrid switching control system
… without operator intervention. As no simple single controller can satisfy these requirements for all setpoint types, a Hybrid Switching Control System is proposed which combines intuitive logic with standard control techniques. Under the guidance of a simple supervisor, the controller …

Analysis and Design of Software-Based Optimal PID Controllers
… hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single …

Efficient capacity allocation in a collaborative air transportation system
… to achieve the same result collectively that a single omniscient entity in control of all decisions in the system could achieve. The typical approach to decomposition employed in optimization, that of modifying the subproblem objectives through a penalty function determined by a master "dual" …

Mixed Modes of Autonomy for Scalable Communication and Control of Multi-Robot Systems
… (MRS) offer many performance benefits over single robots for tasks that can be completed by one robot. They offer potential redundancies to the system to improve robustness and allow tasks to be completed in parallel. These benefits, however, can be quickly offset by losses in productivity …

Synchronization of classes of dynamical networks : analysis and control
… 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 network and …

L1 adaptive output-feedback control architectures
… an existing L1 adaptive output-feedback controller for non-strictly positive real systems based on piecewise constant adaptation law. It is shown that L1 adaptive control architectures achieve decoupling of adaptation from control, which leads to bounded away from zero time-delay and gain …

Head-dependent modelling and optimisation of water distribution systems
… violations of the nodal pressure constraints. A controller-worker approach is implemented to parallelise the optimisation process in which a single controller processor executes the routine operation of the algorithm and employs the workers to carry out fitness evaluation. A real-life network …
