基于模型预测控制算法的太阳跟踪系统
Design of sun tracking system based on model predictive control algorithm
摘要
Abstract
A solar tracking system tailored for mobile platforms has been developed to fulfill the require-ment for high-precision solar position tracking in a vehicle-mounted laser heterodyne solar radiation spec-trum detection system.This study transfers data processing tasks to an edge computing platform,signifi-cantly enhancing processing speed and ensuring rapid system response in dynamic environments.Concur-rently,the integration of camera distortion correction and vision detection algorithms enables precise deter-mination of the solar centroid position within the camera image and calculation of the angular offset.This angular offset serves as the system model's state variable,and the introduction of a model predictive con-trol algorithm facilitates optimal control of the attitude adjustment motor speed,thereby markedly improv-ing tracking accuracy and stability.Experimental results demonstrate a system response delay of only 14.6 ms,with tracking accuracies of 0.13° and 0.04° along the X-and Y-axes,respectively,when deployed on an onboard platform traveling at 15 km/h.The findings confirm that the designed solar tracking system combines high precision with low latency,meeting the stringent demands of heterodyne measurement for precise solar position tracking on vehicle platforms.关键词
