“…Currently the solar panel used is a ground installed with a non-movable panel (Chin et al, 2011). Solar energy, more than any other source, has a unique ability to provide electrical energy at a low cost (Kurian & Nisha, 2015). Solar energy is becoming one of the most favored sources of alternative energy.…”

Our climate system is undergoing severe changes because of a global economy based on fossil fuels and rising greenhouse gas emissions. Furthermore, the use of non-renewable energy will be restricted in the near future. As a result, the use of renewable energy has begun to assist our environment with clean energy. Solar energy is frequently employed since it is a renewable and cost-effective source of power. The objective of this project is to design and implement an automatic solar tracking system by using MATLAB/Simulink and Proteus software to get the maximized power generated from the PV system. In this project, the inventive of an automated solar tracker benefitting from light dependent resistors added with ultrasonic anemometer as a wind sensor and a rotary position sensor to achieve a fully functioning an automatic solar tracker. The values of irradiance and power generated will be discussed on this paper based on the implementation of the Matlab and Proteus simulation.

“…In torque sharing function, reference torque for individual phases are generated due to total reference torque, the reference torque for individual phases are translated into current command signals according to rotor position. Finally, these current references are then compared with the actual phase currents by current controller [5]- [7]. To control the SRM torque directly with lower ripple contents, space vectors can be used.…”

A switched reluctance motor (SRM) has been an alternative solution for electric drives because of its benefit features. The use of such a motor in electric vehicles (EVs) or hybrid electric vehicles (HEVs) requires a control strategy that is capable to develop high torque. SRMs are commonly available in the market with rotor position detectors embedded inside. Problems will appear when such detectors are not symmetrically installed because most of SRM control strategies are commonly based on them. Inaccurate pulses will be generated by the control circuit which finally takes effect on phase current commutation or the beginning of the excitation which is not on proper angle. The use of such detectors is just capable to give information of rotor position in common angles. Improvement for such problems can be done by generating pulses related to the rotor position in smooth angles. In this paper, a control strategy to produce excitation signals with proper angles for SRM stator winding is proposed. By using input capture facility that is commonly available in embedded system, excitation angles can be controlled precisely because a large number of pulses can be produced by the system. Accuracy level of this strategy is determined by TIMER period of embedded system and speed of SRM. To verify the analysis, laboratory experiments were done. They show that the proposed control strategy is capable to rotate the motor with better performance.

“…In recent years, there are several research outcomes based on the method of suppressing torque ripple of SRM. A control strategy based on torque sharing function (TSF) has been proposed in [3–7]. The TSF is used to obtain the expected torque of each phase at different positions of rotor, and then the reference current of each phase is obtained through the table

Referencing to the correlation between electromagnetic torque and winding current of switched reluctance motor (SRM), a novel adaptive fuzzy control method with segmented harmonic currents injection for SRM is presented in this study. The proposed method divides the conduction interval of each phase into n segments and injects the nth harmonic current into the reference current of each phase. The coefficient of the harmonic current in each section is automatically adjusted by fuzzy control strategy according to the torque error. In this case, the current waveform can generate additional torque to suppress the torque ripple caused by the square wave reference current. Also, the novel method can achieve adaptive control over a wide range of load and angular velocity below the base speed. In addition, the control method is flexible, portable, and can be applied to most of the SRM drive systems. The simulation results and experimental results represent that the torque ripple can be effectively suppressed in real‐time by the proposed novel control method.
