Abstract: Facility agriculture is an important component of modern agricultural production, which provides the best growth conditions for plants by regulating environmental factors, such as light intensity, temperature, humidity, and CO₂ concentration．Research progress in greenhouse environmental control technology field at both domestic and international levels in recent years was comprehensively reviewed, practical application and effectiveness of PID control, model predictive control, intelligent control, and internet of things technology-based control strategy in greenhouse environmental management were discussed in depth．Through comparative analysis, various greenhouse control systems' distinctive advantages and potential limitations were revealed, and current greenhouse control systems' challenges and future development prospects were emphasized, aiming to provide a theoretical basis and practical guidance for continuous optimization in greenhouse environmental control, and to promote facility agriculture direction towards more intelligent and precise．
