Utility pipelines are often laid in parallel with overhead high voltage power transmission lines (OHTL). Induced potential on the pipeline due to the electromagnetic coupling (EMC) effect can reach dangerous levels, resulting in potentially unsafe conditions for utility operating personnel and in those areas accessible to the public at large. Such induced potential can exasperate pipeline corrosion and cause undesirable electromagnetic interference on neighboring communication networks. In this paper, a pipeline located close to extra high voltage AC overhead transmission lines (EHV AC OHTL) is studied. In addition, the impact of pipeline location profiles and earth soil resistivity are discussed. The analysis is carried out by using Alternative Transient Program which is the modelling package of Electromagnetic Transient Program Software (ATP/ EMTP).
公用管线通常与架空高压输电线路(OHTL)并联敷设。由于电磁耦合(EMC)效应,管道上的感应电位可达到危险水平,对公用事业操作人员和公众可进入的区域造成潜在的不安全状况。这种感应电位会加剧管道的腐蚀,并对邻近的通信网络造成不良的电磁干扰。本文研究了特高压交流架空输电线路(EHV AC OHTL)附近的管道。此外,还讨论了管道位置剖面和土壤电阻率的影响。利用电磁瞬变程序软件(ATP/ EMTP)的建模包Alternative Transient Program进行分析。

In this paper, robust multiple model-based LSDP (Loop-Shaping Design Procedure) controller is proposed for a SISO system where each linear submodel is represented in the form of a SISO ARX (Auto Regressive with exogenous input) Laguerre model. The proposed controller guarantees robustness in term of stability and reference tracking of the SISO system in presence of parametric uncertainties. Simulation example on the SISO CSTR (Continuous Stirred Tank Reactor) Benchmark is given to show the efficiency and the robustness of the proposed controller in handling the parametric uncertainties of the process.

This paper presents an advanced nonlinear method of a photovoltaic energy chain connected to single-phase network via a single-phase inverter with a filter LCL. In this work, we tried to achieve three objectives of control: (i) the voltage supplied by the photovoltaic panel(PV) must follow the point of maximum power (MPPT),(ii) the voltage across the coupling capacitor must be regulated to ensure the transfer of energy between the two parts,(iii) the current supplied to the network must have a sinusoidal shape and in phase with the grid voltage. To achieve these objectives, we use a nonlinear method based on sliding modes and stability, in Lyapunov's sense, as a mathematical tool for the design of regulators. The simulation results were carried out in Matlab / Simulink. They show that regulators designed achieve their goals.

This paper presents the design and the position control of a robotic rehabilitation didactic system. This robot is an upper limb device simulating the passive rehabilitation of a human elbow joint. The limb dynamic is unknown and differs from one patient to another so only the model of the orthosis robot is identified. Then, experiments were performed without load and three controllers are designed. A comparative study between predictive, PI and RST controllers is established in a real time environment. This comparison highlights the effectiveness of the model predictive controller.

A discrete interval observers used for linear systems attacked by ignorant quantities that previously known only by its bounds, is the main goal for this paper. The most important condition that we are searching for always ensured is the cooperativity. To claim that, two methods are considered as a framework. The presented techniques values are illustrated in an example of simulation and by an application on a transesterification reactor. The obtained results show that it is feasible to have a cooperative dynamic for the observation errors either with a state transformation or by imposing a constraint.

This paper investigates the performance of four-phase Floating Interleaved Boost Converter (FIBC) for vehicular applications. For such applications, current control is indispensable in order to ensure the vehicle power (eventually the current) requirement satisfaction. For this reason, two methods are applied in this work to control the current of the source associated to the studied converter which is a fuel cell in our case. This first method is based on using one current control loop which allows to maintain the total current in the output of the source equal to its reference. The second method consists on improving the first one by applying a current control loop for each converter leg (i.e using four control loops). This converter offers improved efficiency and voltage gain, while ensuring lower input current ripple than other DC-DC boost converter topologies.In this paper, the proposed controls are evaluated for the same road conditions by applying the New European driving cycle (NEDC). Simulation results are presented to validate the effectiveness of the two adopted controls and prove the improvements presented by the technology using four control loops.

In this paper, an observer-based state feedback controller system is designed. A new method based on the Generalized Characteristic Ratio Assignment GCRA is used to set the polynomials of the LQR to reach the desired time specifications such as settling time and overshoot. The GCRA allows to define the weighting matrices Q and R. Then based on the separation principle and the GCRA method a full-order observer is derived and associated with the LQR controller to achieve the robust closed-loop performances. Simulation results are presented.

This paper describes a famous control strategy dedicated to the three-phase bidirectional AC/DC converter called Voltage Oriented Control (VOC). The proposed technique is based on measuring the voltages and currents of the electrical grid in a first phase. Then, the decoupling between the direct current component and the quadrature component of the current, obtained via the Park transform (d–q), will be ensured by what is called feed-forward flow control. The latter is equivalent to using PI controllers. Finally, in order to establish the desired performances, the simulation will be visualized by the Matlab/ Simulink environment.

Frictional losses within the transmission components of robotic manipulators are often modeled as a constant Coulomb friction force or/and a viscous friction force proportional to the sliding velocity. However, the variation in contact forces of lubricated surfaces of the mechanical transmission system influences the friction force. The joint temperature also has an effect on the variation of the latter. Hence, the importance of considering the parameters mentioned in the dynamic model of the robotic manipulator. This paper presents a new load and temperature-dependent model that will be subsequently identified from experimental measurements carried out on two-link robotic manipulator with different loads.
