In this paper, the oily sewage treatment using the technology of ceramic membrane filtration is described. The intelligent control system of distributed sewage treatment is designed. Using multiple ARM processor STM32F103VET6 for each module processing chip, point to point signal transmission through RS232, The operation parameters of each module and its operation status are set up by using several...
A Hybrid Control System (HCS) model has to implement the reaction to discrete events that occur in a controlled plant and as well as to control the continuous time parts according to required behaviors. A certain type of models that includes discrete event and discrete time features is proposed. More than this, the currently proposed models are capable of describing the synchronous and asynchronous...
In multi-controller software-defined networking (SDN) environments, a flow whose path includes switches that are managed by different controllers experiences increased flow setup latency, which is critical for delay-sensitive applications. To address the issue, we propose an optimal controller assignment scheme that minimizes the average flow setup latency while limiting load imbalance between controllers...
This paper explores the use of a learning algorithm in the "guarding a territory" game. The game occurs in continuous time, where a single learning invader tries to get as close as possible to a territory before being captured by a guard. Previous research has approached the problem by letting only the guard learn. We will examine the other possibility of the game, in which only the invader...
The original approach to the realization of digital differential-integral fractional order controller for electromechanical systems by using first and second order Oustaloup transformations has been put forward. The research results of prototypical controller based on Atmel ATMega2560 and Atmel ARM ATSAM3X8E microcontrollers have been described.
This paper deals with the simulation and modelling of a Quadruple-Tank interacting system using various controllers. Quadruple-Tank is a one kind of MIMO (Multiple Input Multiple Output) system. It is not possible to determine all the parameters used in Multi variable systems. The major issues in a multivariable process are that loop interaction can arise and causes difficulty in design of feedback...
It proposes a new detection system to detect handlebar appearance based on machine vision technology. This system is mainly composed of motor drive module, communication module, image processing module, operation control module, etc. System mainly uses image processing technology to process the information of detected object collected by camera in order to determine whether the detected object can...
Remora III, a 6,000-meter rated Remotely Operated Vehicle (ROV) designed, built, and operated by Phoenix International Holdings, Inc. (Phoenix), has performed extremely well during its 16 years of service as a search and recovery vehicle. While several mechanical upgrades have been made to the vehicle during this period, the desire to increase Remora's service capability and operational availability...
Under the 10th Malaysia Plan, National Defense University of Malaysia (NDUM) has developed a new naval architecture laboratory to suit the requirement as a niche and boutique university for new knowledge and competencies in defense related disciplines. This paper describes the optimal specification and design of a wave test flume in a confined space. The wave maker was specified with the constraints...
Connection setup in software-defined networks (SDN) requires considerable amounts of processing, communication, and memory resources. Attackers can target SDN controllers with simple attacks to cause denial of service. We proposed a defense mechanism based on a proof-of-work protocol. The key characteristics of this protocol, namely its one-way operation, its requirement for freshness in proofs of...
Cyber-Physical Systems (CPS) are yielding novel problems and solutions for security researchers. CPSs connect computerized controllers and human supervisors with physical systems used in the energy, transportation, water, manufacturing, and other sectors. Recent attacks against CPS have prompted unprecedented investigation into new threats and mitigations against CPSs. There are motivating examples...
This paper looks into the intelligent control system design using fuzzy logic for Multiple Input Multiple Output (MIMO) systems, with a case study application of a depyrogenation tunnel [1]. Depyrogenation tunnels are widely and specifically used in pharmaceutical filling process for removing pyrogens adhere to containers (sterilization treatment of containers mainly). As part of the research process...
In order to detect the nonlinear characteristics (flow hysteresis) of aviation fuel valves and to improve the accuracy and efficiency of fuel valve performance test, a computer aided fuel valve automatic test system is designed. The test system mainly consists of industrial control computer, data acquisition card, signal conditioning circuit and test software developed on the LabVIEW virtual instrument...
The presence of delays makes system analysis and control design much more complicated. Delays deteriorate the control performance and could destabilize the overall system in the theory of discrete-time signals and dynamic systems. Whenever a computer is used in measurement, signal processing or control applications, the data as seen from the computer and systems involved are naturally discrete-time...
In this paper, a generalized Radio Frequency Identification (RFID) control using posture effect on Ultra High Frequency (UHF) RFID tag detection is proposed. The idea is based on the polarization characteristic of passive tag antenna. When it is placed in horizontal and vertical orientation, the Received Signal Strength Indication (RSSI) measured by the reader antenna will be distinct. Based on the...
The train driver controller is a main electric appliance for the train speed controlling and braking. Its reliability relates directly with the driving safety. The existing life-span test system of the train driver controller can only detect the mechanical life-span. A new life-span test system is developed which can detect not only the mechanical life-span, but also the life-span of the electrical...
