This study investigates a high friction fruit conveyor system based on a traditional frictionless ball-and-beam system (BBS). Both share commonalities of behavior i.e. controlling an object by manipulating the platform angle. The BBS system includes a rubberised strip to make increase its friction slightly. The inherently unstable BBS is stabilised with a simple PID controller to permit system identification...
Interaction with non-rigid objects poses a challenge for manufacturing systems. The dimensions, locations and physical properties of soft-tissue objects like fruit or meat are subject to considerable variation and uncertainty. Possible ways to accommodate this are to use a number of different types of sensors and actors. However, a control system physically located next to a manufacturing system is...
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...
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.
The emerging 5G networks will enable control-oriented applications where sensors, actuators, processors and controllers are geographically distributed and wirelessly connected. One major challenge of networked control systems (NCSs) is how to guarantee the stability of all control loops in the presence of communication delay. Addressing this problem, the control community generally focuses on designing...
In this paper, the problem of developing a model for signal control system with transit priority using Colored Petri Nets (CPNs) is considered. In a regular four phases signal lights control model, transit detection and two kinds of transit priority strategies are integrated to obtain Colored Petri Nets based transit priority signal control model. The resulting model ensures that transit can pass...

In the list of original elements of the concept of building highly reliable, fast-reconfigurable interactive test monitoring and control systems: — using of original technology of representation...
The control and steering system for testing flow is presented in this publication. Multi-phase flow measurement technologies are still built and improved. There is a clear trend in the industry to implement more optimum related functions, where the focus is on active control and the monitoring system. Control related active optimum functions can only be realized with a system that allows electronic...
In this paper, the suboptimal control problem is addressed for a class of discrete time-varying systems subjected to the stochastic communication protocol (SCP). The measurements provided by the sensors are transmitted through the communication channel and then fed into the controller. The SCP is utilized to select the sensor getting access to the communication media. In presence of the nonlinearities,...
Article deals with the automated dispatch control system (ADCS) is designed to improve the reliability and efficiency of operational dispatch and process control facilities that are part of the power system. ADCS is a set of hardware and information of the software used in the dispatching management of energy facilities based on computer. The proposed model of simulator ADCS and automated system commercial...
In this paper we discuss the Internet of Things (IoT) by exploring aspects which go beyond the proliferation of devices and information enabled by: the growth of the Internet, increased miniaturization, prolonged battery life and an IT literate user base. We highlight the role of feedback mechanisms and illustrate this with reference to implemented computer enabled factory control systems. As the...
In non-contact-type sensors, sensing may temporarily fail and indicate outliers due to occlusion. To address such failure, this paper proposes to adopt a two-degree-of-freedom (2DOF) structure with learning feedforward control. This structure turns out to be more tolerant than mere one-degree-of-freedom (1DOF) control in terms of response performance which is verified through both simulation and experiment.
This paper combines coverage control, random-walk and artificial potential method to deploy multi-copter type Unmanned Aerial Vehicles (UAVs). With the coverage control, it is able to deploy agents in the coverage area with arbitrary distribution based on the purpose of control. However, when initial position of agents concentrates on one location, it could be fallen into the local optimal solution...
This paper presents new approaches for construction of knowledge-oriented control systems. The AND/OR-graph model is improved for control rules visualization and interactive processing. The knowledge-oriented system for the dispatcher that regulates the safe operation with electrical equipment made it possible to increase the reliability of decisions taken by the dispatcher by 12%.
This paper focuses on a possible evolution of the control architectures suitable for Integrated Power Systems in modern all-electric ships. In control systems there is a major trend in using information and telecommunication technology as general real-time operating systems and standard communication protocols. This trend leads a standardization at software and communication protocol level that is...
In this paper, present a vehicle actuator response using a hybrid control and make the vehicle has electronic stability program. Electronic Stability Program (ESP) is an automatic stability control systems on vehicles. Where the system works to avoid understeer and oversteer conditions when the vehicle is turning. Understeer is a condition where the vehicle more difficult to turn, this is because...
The transition from a model-driven to a requirements-driven approach in the software development for programmable logic controllers will allow the developers to focus on the proper definition of the problem which needs to be solved and let the computer find a suitable solution for it automatically. This article presents a domain specific language intended to support this transition. The main focus...
The active vibration control of SFSF (Simply Supported-Free-Simply Supported-Free) smart plate by using linear quadratic Gaussian (LQG) controller is described in the paper.
