Abstract：Taking open ⁃ plan offices as the research object,an intelligent lighting control system which adjusts the illuminance based on daylighting and user demand is proposed;each lighting fixture and working face in this lighting system is separately equipped with an illuminance sensor and an intelligent unit to provide illuminance information and individual setting value of each working face for the central control unit. On this basis,the dynamic control model of lighting system is established and the constrained control algorithm is employed to determine the optimal dimming value of lighting fixtures,and the energy consumption of lighting fixtures and energy consumption of switches are used as the objective function of the lighting system. DIALux software is used to verify this intelligent lighting system and control method,and the results indicate that this control strategy can automatically realize the real⁃time dimming based on the changes in outdoor daylighting and users individual demand and also reduce the service time of lighting fixtures and save energy.

摘 要：以开放式办公室为研究对象，提出一种基于自然光和用户需求调整照度的智能照明控制系统，该照明系统中每个灯具和工作面分别配备有照度传感器和智能单元向中央控制器提供工作面照度信息和个性化设定值。在此基础上建立照明系统动态控制模型，并利用约束控制算法确定灯具的最佳调光值，其中灯具的能耗及开销能耗作为照明系统的目标函数。通过利用DIALux软件对该智能照明系统及控制方法进行验证，结果表明：该控制策略可依据室外自然光的变化和用户的个性化需求进行实时自动调光，可减少灯具的使用时间，节约能源。
