Optimal material level control in blending tank can be achieved through the use of a PID controller. However, the major challenges of PID controller are high overshoot and steady-state error, prolong settling time, and slow response which practically causes wastages and equipment downtime. Thus, in this work classical techniques were employed to tune PID controllers to achieve optimum performance of the blending tank level control. The mass balance principle was used to model level of the blending tank while Zigler-Nichols (ZN), Chien-Hrones-Reswick (CHR), and Cohen-Coon (CC) techniques were used to tune the PID controller for optimal performance. The performance of the simulated control schemes MATLAB/Simulink were evaluated using rise time, settling time, peak amplitude, and overshoot. The results revealed that the ZN-PID controller gave the lowest rise time of 2.11s, settling time of 14secs, and peak amplitude of 1.04 while the lowest overshoot of 0% was achieved by both CHR and CC-PID. It can be inferred that ZN-PID gives the best way of controlling the level of the blending tank.

The maximum power point tracking techniques are used to fully exploit the power output of the photovoltaic panel. This power always varies with the Photovoltaic solar irradiation and the atmospheric temperature. However, with the progress of power electronic equipment, solar panels may now be operated at their maximum power point, increasing total Photovoltaic system efficiency. Simple and Quadratic boost converters are simulated and the results are compared in this study. Then, the MPPT technique based on Incremental Conductance is proposed to improve the efficiency of the Photovoltaic system. For dynamic solar irradiance and temperature, the suggested technique's performance is simulated using MATLAB/Simulink. The analysis is based on two systems that use different DC-DC converters.

In recent years, the implementation of collaborative strategy in logistics systems has become a highly efficient practice to realize economic as well as environmental benefits. Traditionally, the collaborative logistics network design problem is based on classical and independent models where each planning decision is made separately. This study presents and solves an integrated and collaborative two-echelon location, inventory and routing problem to design sustainable distribution networks. Due to the NP-hard nature of the investigated problem, a two-stage heuristic approach is developed to deal with large real-world problems. To assess the performance of the proposed approach, a comparative study of the obtained results with those obtained by the CPLEX solver is performed. The comparison results demonstrate that the heuristic approach is very efficient in terms of computation time and solution quality. In addition, a real case study in the French agri-food sector is discussed to analyze the sustainable gains of the proposed approach. The findings reveal that cooperation in integrated decision management can significantly reduce emissions, accident risk as well as logistics costs.

Asynchronous drives are widely used in many industrial applications because of their low cost, high performance and robustness. However, faulty operations may appear during the lifetime of the system. This paper deals with the use of motor current signature analysis (MCSA) as a diagnostic technique for the influence of V-belt drive faults on three-phase induction motors. For this purpose, we create faults on the belt such as axial misalignment and side-cut-off fault.

This research document deals with the synthesis of a nonlinear control law for a doubly fed induction generator (DFIG), which aims at improving its performances, robustness, and stability. Several commands have been proposed in literature, among them, the adaptive nonlinear backstepping command based on Lyapunov function. The purpose of this command is to control the electromagnetic torque of the generator while maintaining a reactive stator power equal to zero. This command permits the extraction of the maximum power point, despite wind speed variations. In order to validate the theoretical results, the corresponding algorithm is implemented in MATLAB/SIMULINK simulation environment. The results analysis shows the characteristic robustness of the DFIG using the proposed controller.

Disabled persons and the elderly face many problems in their daily lives. Mobility is one of the most common of these problems. Electric wheelchairs are among the most frequently used devices to help them navigate. However, safety remains one of the biggest problems for these wheelchairs. This paper proposes an electric wheelchair monitoring system based on the Internet of Things (IoT) and Fog computing to provide safety for the users. This system was developed using the NodeMCU V3 IoT platform and an Android app that plays the role of Fog server, which allows users to monitor the ambient climate factors and the battery level, communicate with healthcare providers, and receive notifications and recommendations if there is a risk. Through evaluation, most potential users of this system consider it easy to learn and use, suggesting that our proposal can improve the safety of wheelchairs users.

We propose in this paper the study of the dynamic behavior of the JFET Normally-off based on 4H-SiC (1200V-17A), which depends on junction capacitances between the electrodes. The evolution of these capacitances as a function of the applied voltage shows the non-linearity between these parameters. The dynamic behavior in switching of the JFET has been studied and compared with the results found by simulation using PSPICE. According to the forms of experimental and simulation waves, we have able to extract the switching time: turn-on Ton and turn-off Toff which are low ( of the order of 10-6s) and still proves the rapidity of the switching speed of these transistors.

Novel high speed, low voltage (LV) low power (LP) current mode digital to analog converter (DAC) using the conventional technique (GD) an unconventional technique bulk driven quasi floating gate technique (BD-QFG) is presented in this paper. The performance of the proposed DAC has been simulated using the GD and the BD-QFG technique. The DAC based in the BD-QFG showed high performance in terms of dynamic performances, supply voltage, and power consumption in comparison to the GD DAC. The conventional and unconventional 4 bits DAC has been simulated in 0.18 μm CMOS technology. The proposed circuit has been simulated through an ELDO simulator. The BD-QFG DAC achieves a bandwidth (750 MHz), low power consumption (0.114 mW), low supply voltage (0.8V).

Parallel hybrid car is composed of an internal combustion engine, a reversible electric machine and a battery. The heat engine is powered by chemical energy stored in the fuel. For vehicle traction, the two machines can operate at the same time or separately. The battery can be charged at the same time with the vehicle's traction or while it is stopped, we speak of hybrid mode with battery charging. One can also take advantage of energy recovery by enumerative braking along a road downhill or / and during a deceleration of the speed of the car. In the event that the vehicle is only towed with the electric machine, this is referred to as pure electric mode. The case where the two machines intervene at the same time to the traction of the vehicle corresponds to the assistance mode. Like the conventional car, the hybrid car can operate in pure thermal mode. In actual operation of the vehicle, the route is unknown in advance. To minimize fuel consumption, the powertrain system must operate instantly at its best fuel efficiency. This work deals with the case where the vehicle route and driving conditions are unknown in advance (real case). In this condition, we propose an optimal control strategy based on instant criterion that we have developed. These allow the maximization of the overall and instantaneous efficiency of the powertrain system of a parallel hybrid vehicle in each mode of operation.
