We propose herein a data-driven dead-zone (DZ) compensation strategy using a model-free Virtual Reference Feedback Tuning (VRFT) approach. The VRFT tuning scheme is accommodated for two controller structures: the first one which explicitly includes a model of the DZ inverse to be identified and the second one which uses a Neural Network (NN) to model the controller to be identified. The main question...
This electronic document is a “live” template and Abstract: Questions of formalized description of planning and control processes for new class — three levels adaptive manufacturing control system were considered. It were marked them special features that allow to formed demands to methods of process description. It was showed that suggested homogeneous method suits fine for mathematical description...
This article presents a real-time control system for an experimental model of a water distribution system. The hardware and software implementation follows the latest trends in IoT and proves that such an architecture can be used for real-time process control in distributed systems. The control of flow is implemented using a multiple-model control algorithm for the pumping station. A method which...
Automation systems, as well as process control, has played a key role in the industry nowadays. For good system performance, it is necessary that mathematical model is closest to the real model, which is detailed in this work. The objective of this study is to present a modeling (considering the viscous friction), stability analysis and simple PID controller tuning using as an example, an arm with...
For complying with power distributor regulation, the electric car chargers have to address the line current harmonic mitigation problem. The conventional solution is a proportional integral controller on the rectified current with a feed-forward anticipation action on the input network current. In this work we take advantage of a harmonic description of the electric car charger in order to propose...
Electric Vehicles (EV) have become increasingly popular in recent years and are regarded as an important means to alleviate air pollution problems. The broad connection of EV batteries to the grid along with household scale renewable energy sources penetration creates the need for local unified control systems to support the future smart grid. In this paper, an Energy Storage Management System was...
In this paper, a three loop control strategy (TLCS) based on decoupled zero voltage switching angle (ZVSA) loop is proposed for a series-series (SS) compensated wireless power transmission (WPT) system. To realize constant current charging for EVs and ZVS operation of primary inverter, variable frequency and phase shift control strategy (VF-PSC) is adopted. However, the control variables that are...

In this study, the data obtained from the automated aquarium system: aduarium and the tests made with this system are shared.
Outlier-tolerance is the important part to the safety studies of technology process, and it is also one of the key technologies that can guarantee the operation safety of the dynamic system. Firstly, how to realize the safe and reliable processing of fault and outliers is discussed. This paper analyzes the significant differences that exist in the three kinds fault tolerance research branches which...
There are many function modules in the numerical control (NC) system, the system needs to communicate with each other through the data interaction among modules, to coordinate the work between modules and complete the control task. In this paper, the main function module structure of NC system is constructed based on RCS method. The communication between the NC system modules is realized by using...
This report shows that the architecture of Big Banks' Management Control Systems can be presented as a two or three-tier structure without separating the functional components to the front and back office. The report also examines the key legislative and regulatory documents that define the specific requirements for the Big Banks' Management Control Systems' Software. Functional components' classification...
The present paper considers a problem of assessment of cybersecurity architecture of modern digital control system using a formal hierarchical model of the cybersecurity policy. As a basis for formal security model the extended discretionary take-grant security model is presented. The formal technique used to provoke thoughts about the way how the rights and information may be passed along the systems...
The need to improve the quality of management at minimum costs, the complexity of the structure of the management object, the functions performed by it, leads to an increase in uncertainties that need to be taken into account.
This paper proposes a novel architecture for control systems of modular reconfigurable robots that combines centralized and decentralized approaches to achieve the best ration between efficiency, fault-tolerance and cost-efficiency.

This paper presents the systematic design and performance of two controls for half-bridge converters with LCL output filters based on a similarity transformation. This type of converters is commonly used in, for example, grid or battery interfaces. Both controls feature active damping, i.e. filter resonances are damped through software and not by using passive resistors. Moreover, both controls are...
