This research deals with the design and simulation of a solar power system consisting of a KC200GT solar panel, a closed loop boost converter and a three phase inverter by using Matlab / Simulink. The mathematical equations of the solar panel design are presented. The electrical characteristics of the panel are tested at the values of 1000 for light radiation and 25 °C for temperature environment. The Proportional Integral (PI) controller is connected as feedback with the Boost converter to obtain a stable output voltage by reducing the oscillations in the voltage to charge a battery connected to the output of the converter. Two methods (Particle Swarm Optimization (PSO) and Zeigler- Nichols) are used for tuning PI controller to enhance the overall performance of the system. The Sine Pulse Width Modulation (SPWM) technique was used to obtain a pure 3-phase in low distortion. The voltage and current output values of ± 14V and ± 2.8A are obtained, and the Total Harmonic Distortion (THD) value is 4.20%.
In homes and any processes industry, the main processes that need to be controlled are temperature and level of the water. This paper is focused on the design and implementation of an Electric Heated System that connects with their environment using actuators and sensors for sensing and control the temperature and level of the water. Also, the mathematical models for operation principle are presented. The system used the arduino UNO card which is a microcontroller board for controls 'ON' and 'OFF' conditions of the heater and motor depending upon the temperature and level of the water in the tank. There are three sensors used with arduino, First: the Ultrasonic sensor (HC-SR04) is used to measure the distance between the sensor and the object, and this distance is proportional to the level of the water. Second: Infrared sensor (KY-032) is used to control the drain of water by opened and closed of solenoid valve. Third: The sensor (DS18B20) is used to sense the temperature to prevent excessive in temperature that can lead to serious accidents. The Android device communicating with a Bluetooth module connected to an arduino Uno microcontroller. The andriod application is used for two tasks. First monitoring the value of the temperature and water level in the tank during the operation of the system, second the wireless communications technique is used to turn ON and OFF the system.
The aim of this paper  is to use an economical technology to built the liquid tank level control the liquid level using arudino UNO microcontroller as data acquisition with LabView software interfacing with ultrasonic sensor. The ultrasonic sensor is used for better accuracy and stability in different conditions. The front panel of labview is display the liquid level in the tank, and the status of motor, (ON or OFF) depending on the level of the liquid. The developed system is highly flexible and easy in controlling the liquid tank level. The mathematical model of the system, MATLAB simulation results have been achieved using software.
