Abstract:

In this study, a dynamic model of a solar array drive system that includes a pair of flexible solar arrays with a central rigid shaft and a permanent-magnet synchronous motor (PMSM) was developed, and a disturbance compensation sliding mode control (DCSMC) strategy was proposed to realize the speed smoothing and vibration suppression control of the system.

Abstract:

To improve the Solar Array Drive Assembly (SADA) system, a servo control method known as Linear Active Disturbance Rejection Control (LADRC) is introduced, utilizing a speed loop for a Permanent Magnet Synchronous Motor (PMSM). This method serves as an alternative to the conventional proportional–integral (PI) controller, which exhibits a limited stability margin. The use of the LADRC controller leads to decreased overshoot and enhances the system’s robustness against disturbances. First, the mathematical representation of the PMSM alongside the dynamic model of the solar wing is established.

A sun-tracking solar array is an effective solution to the increasing energy demand of spacecrafts. However, the driving torque fluctuation of the solar array driving assembly (SADA) and its oscillatory motion lead to the micro-vibration problem of the spacecraft. In this article, a disturbance torque model of the sun-tracking solar array, which takes its friction and flexibility into consideration, is established. Furthermore, a test platform was built to measure the disturbance force/torque, and a solar array simulator (SAS) was designed to replace the solar array in the ground experiments.

The use of chemical bonds to store solar energy is a promising approach to address the intermittency of the sun by harnessing sunlight to drive chemical transformations.

Abstract:

This paper presents an innovative approach to achieve efficient solar water pumping through the integration of a Photovoltaic (PV) array and a Brushless Direct Current (BLDC) motor water pumping system. The system incorporates a Voltage Source Converter (VSC) with six switches, utilized to facilitate commutation. The inherent solar radiation is harnessed by the PV array, capitalizing on its renewable nature to generate electricity. By dynamically adjusting the switching states of the six VSC switches, the speed of the BLDC motor is modulated in response to the varying levels of available solar

Abstract:

The dynamic performances of a permanent magnet synchronous motor (PMSM) and an asynchronous motor (ASM) connected to a photovoltaic (PV) array through an inverter are analyzed. The mathematical models of PV array, inverter/motor and controller are developed. The photovoltaic array is represented by an equivalent circuit whose parameters are computed using experimentally determined current-voltage I-V characteristics. The necessary computer algorithm is developed to analyze the performance under different conditions of the solar illumination for pump load. The study also examines the effectiven

Abstract:

The solar tracking system keeps a solar collector with its responsive surface normal to the solar rays. It consists of a shaft supported for rotation approximately an axis parallel to the north-south axis of the earth, a stepper motor for intermittent rotation of the shaft at an average rate equal to rate of rotation of the earth. A solar collector securing assembly is placed on one side of the shaft and consists of a bracket, collars securing the bracket to the shaft, a guide for fixing a solar collector pivoted to the bracket about a pivotal axis transverse to the shaft to differ the inclina
