摘要

This study explores an adaptive forward-looking control method for solar heat energy systems, focusing on improving short-term recovery and system output during changing sunlight levels. Current control ways use mostly fixed models or simple gain–reset logic, which fail to keep steady heat levels and actuator working ability during changing outside weather. These ways often react slowly to sunlight shifts, causing energy waste and more damage to moving parts. To solve these weak points, a flexible model-based prediction control plan is shared. The hard part is to keep a good mix of forecast quality, fast system reaction, and part safety without causing delays in running the control tool. Solving this hard part is important, as steady solar heat control helps directly in saving energy and system health. The study aims to build and test a control setup that can react before sunlight changes happen. A MATLAB/Simulink-based setup is used, adding sunlight prediction data and heat flow features. Main system checks include heat difference, size of valve action, return time, and heat use rate—picked based on how the system reacts to sunlight shifts. Test data is made by fixed-case runs of sunlight drop events and studied using signal test plots, control signal shape checks, and sun change-based control steps. System checks focus on lowering heat change, lowering control signal force, and raising energy output. When compared with the initial standard models, the results show strong gains in many system checks. To be clear, return time drops by more than heat use goes up by close to optimum points, and valve use is cut down by up to huge percentage. While this method works well in test sun-drop cases, later works must focus on system growth, long-term part use, and working with backup energy parts.
