This paper presents a method of test , estimation and predication of some state parameters of the power unit in power and electric equipment , these parameters can be temperature , voltage , current and so on ; when attaining the values of these parameters at the next state , whether the power unit will go into the malfunction or not can be knew , according to the result , some measures can be made ; by controlling the values of correlative parameters , the unit could be maintained in its optimal running status ; so the damage to the power unit can be prevented , the running quality of the driving system can be guarantied , and the optimized control level of the system can be improved 本论文提出了一种利用预测估计的方法,对电力电子设备中的功率器件的某些主要状态参量(如:温度、电压和电流)进行测试、估计并预测,从而得出未来的运行状态;然后据此判断该功率器件是否已进入故障范围,以便提前采取措施,通过对相关参数的调整来保证功率器件始终工作在最佳状态;这样,既避免了功率器件损坏的发生,又避免了驱动系统故障状态的出现,明显地提高了系统优化控制的水平。
