摘　　要：针对大功率紫外灯启动的电流控制问题,提出了一种基于模型预测实现电子镇流器的控制方法。首先建立了电子镇流器的数学模型,以该模型为基础构建了系统控制的预测模型,通过采样经过三相不控整流和滤波之后的直流电压值和Buck电路的电感电流值建立平均状态方程,以最优性能为指标,求解最优开关状态,对电子镇流器电路进行控制。仿真及实验表明该模型预测控制器在紫外灯点火启动过程中具有良好的动态性能,有效控制了电子镇流器。This paper presents a controlling method for electronic ballast based on model prediction aiming at the current control problem of high-power ultraviolet lamp startup,firstly establishes the mathematical model of electronic ballast,builds the prediction model of system control on the basis of the model,constructs the average state equation by sampling the direct current voltage after three-phase uncontrolled rectifier and filtering and inductance current value of Buck circuit,takes optimal performance as the index,solves the optimal on-off state to control the electronic ballast circuit.The simulation and experiment show that the model prediction controller has good dynamic performance in the ignition process of ultraviolet lamp and controls the electronic ballast effectively.
