“…Ibbini and Adawi [9] a dual maximum power point tracker (dual-MPPT) was presented and simulated using MATLAB SIMSCAPE to get the global maximum power point (GMPP) under partial shading conditions for a solar photovoltaic module. Dual maximum power point (MPP) trackers are more efficient than conventional single MPP trackers and have more sensitivity to partial shade.…”

<span>Renewable <span>energy plays a crucial role in the modern life. It has several forms, such as wind, hydroelectric, and solar energy. The latter is the most popular energy sources in wide areas. In order to maximize the generated energy from solar panels, these panels should be placed and remain in a vertical position with the sun rays. Therefore, a novel system is proposed in this paper to track the sun rays through designing and implementing a solar tracking system with hybrid controller type (controllino), which a hybrid controller that combines the programmable logic controller (PLC) and microcontroller. This leads us to mix the advantages of PLC and microcontroller thus, get fast and flexible control with several input and output which makes the cost is very low and the software is free and unprotected from the production companies. The system that has been built is controlled by self-controller which has the ability to track the position of the sun and control on the movement of the solar panel in order to keep the direction of the solar panels perpendicular to the sun. As a result, the efficiency will increase without the need to identify the geographical location where the solar panels are located and reduce the cost of generating energy by requiring a minimum number of solar panels.</span></span>

“…Therefore, K must be designed to ensure that condition (34) is fulfilled. This is done by calculating the settling time of the PV voltage from (33), which is given in (35) for the classical band of 2%:…”

“…TheĆuk converter has been also used for DMPPT applications with several limitations. For example, the work reported in [34] demonstrates the advantages, in terms of power production, of a DMPPT system based onĆuk converters. However, such a work does not consider any control system to compensate the load perturbations, hence it is not evident that such a system will be stable under real operation condition.…”

The wide range of step-up and step-down input-output voltage characteristic of the Cuk converter makes it a good candidate to interface photovoltaic arrays in both classical and distributed maximum power point tracking systems. Because its two inductor structure, Cuk converters have continuous input and output currents, which reduce the additional filtering elements usually required for interfacing dc/dc converter topologies. However, PV systems based on Cuk converters usually do not provide formal proofs of global stability under realistic conditions, which makes impossible to ensure a safe operation of the PV installation. Therefore, this paper proposes a high performance sliding-mode controller for PV systems based on Cuk converters, which regulates the PV voltage in agreement with the commands imposed by a MPPT algorithm, rejecting both load and environmental perturbations, and ensuring global stability for real operation conditions. Finally, the performance of the regulated PV system is tested using both simulations and experiments.

“…MATLAB/simscape multibody provides a powerful quasi-physical simulation environment for multi-component mechanical systems such as robots, multibody systems, hydraulic and pneumatic systems. The simscape-based approach has been exploited successfully in several studies, e.g., [27]- [29]. Simscape multibody gives blocks representing links, joints, sensors, and torque/force components that make the simscape-based model conformable to the actual robot.…”

Actuators in a robot system may become faulty during their life cycle. Locked joints, free-moving joints, and the loss of actuator torque are common faulty types of robot joints where the actuators fail. Locked and free-moving joint issues are addressed by many published articles, whereas the actuator torque loss still opens attractive investigation challenges. The objectives of this study are to classify the loss of robot actuator torque, named actuator torque degradation, into three different cases: Boundary degradation of torque, boundary degradation of torque rate, and proportional degradation of torque, and to analyze their impact on the performance of a typical 6-DOF robot (i.e., the IRB 120 robot). Typically, controllers of robots are not pre-designed specifically for anticipating these faults. To isolate and focus on the impact of only actuator torque degradation faults, all robot parameters are assumed to be known precisely, and a popular closed-loop controller is used to investigate the robot’s responses under these faults. By exploiting MATLAB-the reliable simulation environment, a simscape-based quasi-physical model of the robot is built and utilized instead of an actual expensive prototype. The simulation results indicate that the robot responses cannot follow the desired path properly in most fault cases.
