  • Free-surface flow simulations for discharge-based operation of hydraulic structure gates

    We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in the operation of hydraulic structure gates. A water level-based gate control used in most of today's general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar ...

  • Healthy Control Valves

    A simple maintenance routine can help ensure trouble-free valve operation. Whether the control valve in your system is the first one that has required maintenance or if you are experienced with maintaining multiple valves in your system, some simple guidelines can help keep them operating at optimal performance. Physically checking all valves at least every 12 weeks is important, assuming that ...

  • A novel digital implementation of AC voltage controller for speed control of induction motor

    In this paper, a novel, simple and reliable digital firing scheme has been implemented for speed control of three-phase induction motor using ac voltage controller. The system consists of three-phase supply connected to the three-phase induction motor via three triacs and its control circuit. The ac voltage controller has three modes of operation depending on the shape of supply current. The ...

  • SeReCon: a secure reconfiguration controller for self-reconfigurable systems

    A risk of covert insertion of circuitry into reconfigurable computing (RC) systems exists. This paper reviews risks of hardware attack on field programmable gate array (FPGA)-based RC systems and proposes a method for secure system credentials generation (unique, random and partially anonymous) and trusted self-reconfiguration, using a secure reconfiguration controller (SeReCon) and partial ...

  • Automated fuzzy decision and control system for reservoir management

    Traditional approaches to the management of an artificial reservoir involve the use of linear, dynamic, nonlinear or stochastic programming. Hence a purely model-based approach would be extremely difficult and thus, recently, a large number of papers devoted to the solution of reservoir management problems based on fuzzy logic approaches have appeared. In this work, two management problems of a ...

  • Controlling the water level of a river dam case study

    SmartScan25 provides an efficient solution for controlling water level of the Wardha river reservoir from a distance of 40m (131ft) thus preventing draughts and floods to the district of Amravati, India. Upper Wardha Dam is build up on the Wardha River at a height of 36m (118ft) and 7km (4.35mi) length and situated on the boundary of Amravati and Wardha Districts, India. Controlling the water ...

  • Real Time Control of the Sewage System in St Malo

    Saint-Malo is an extremely attractive and popular seaside resort on the north coast of Brittany in France. Covering 1,400 hectares, the local population of 50,000 increases to 120,000 in the tourist season. One of the distinguishing features of this part of the Channel coast is a very high tidal range – 14 meters from low to high, with a potential impact back through the sewer network. Combined ...

  • Corrosion resistant FRP reduces maintenance issues for water and wastewater treatment and control

    At this Wastewater Treatment Plant in Glendale Heights, IL, an aluminum slide gate had to be forced open using a front-end loader and a chain after seizing in place due to inevitable corrosion. The corrosive bond was so severe that the chain snapped upon the first attempt. The water and wastewater treatment and control industry is a prime example of how constant exposure to toxic elements can and ...

  • Contribution to a flood situation management: a supervisory control scheme to reduce disaster impact

    Inundations due to river overflows are becoming more frequent; management of flood is thus an important task belonging to the set of preventive measures allowing the protection of people and goods downstream. The flood situation management method proposed in this paper was designed to reduce the flood impact at its early arising stage. The river is supposed to be equipped with reservoirs in ...

  • Boundary feedback control of an open canal with arbitrary cross sections

    This paper deals with the boundary feedback control of an open channel with arbitrary cross sections, which is modelled by the nonlinear Saint-Venant equations. The characteristic form of the Saint-Venant initial-boundary value problem is established in terms of Riemann invariants. In order to develop the boundary feedback control laws for a canal with arbitrary cross sections, the simplest ...

  • Torque and flux ripple minimisation in direct torque control of induction motor using space vector modulation

    This paper explains the application of Space Vector Modulation (SVM) technique to reduce torque and flux ripple in an induction motor employing Direct Torque Control (DTC). The effective time is determined using imaginary time vector, thereby the lengthy procedure of using reference voltage vector is eliminated, and also the sector identification and angle determination are not used. Simulation ...
