项目摘要

De-icing or defrosting a transparent windshield is a critical operation concern in many applications such as cars, airplanes,**locomotive, and sea vessels. The de-icing process in these applications consumes excessive time and energy due to the variable**parameters that affect the frost formation such as ambient conditions, windshield geometry, and the vehicle speed. Pulse-Electro**Thermal De-Icing (PETD) technique is proposed as an advantageous method that can remove the ice efficiently in a very short**time period. PETD technique utilises a powerful electrical pulse that leads to melting the interfacial layer of ice at the contact**surface between the frost and windshield glass. Pre-set controllers wont provide premium efficiency and may require manual**adjustment from the end user because the efficiency of the PETD technique depends on many variable parameters such as the**outside temperature, frost type and thickness, windshield geometry and inclination as well as the power availability. Hence,**adaptive control approach is needed to modulate the necessary output parameters such as the pulse power, frequency, duty cycle**and distribution based on the variable input parameters. This adaptive control unit should instantaneously measure these external**parameters and run them through internal control algorithm in order to provide the optimum output parameters to achieve the best**efficiency. Therefore, the objective of this research project is to develop an adaptive control strategy that can effectively be used to**operate the PETD technique in an automotive windshield.**

在许多应用中，诸如汽车，飞机，**机车和海船等许多应用中，透明的挡风玻璃进行除冰或解冻是一个关键的操作问题。由于影响霜冻形成的可变**参数，例如环境条件，挡风玻璃的几何形状和车辆速度，这些应用中的冰期过程会消耗过多的时间和能量。提出了脉搏电子**热除冰（PETD）技术，作为一种有利的方法，可以在很短的时间段内有效去除冰。 PETD技术利用了强大的电脉冲，从而导致在霜玻璃和挡风玻璃之间的接触表面上融化冰层冰层。预设控制器不会提供高级效率，并且可能需要对最终用户进行手动调整，因为PETD技术的效率取决于许多可变参数，例如**外部温度，霜冻类型和厚度，挡风玻璃的几何形状和倾斜度以及功率可用性。因此，需要**自适应控制方法来调节必要的输出参数，例如基于变量输入参数的脉冲功率，频率，占空比**和分布。此自适应控制单元应立即测量这些外部**参数，并通过内部控制算法运行它们，以提供最佳的输出参数，以实现最佳的**效率。因此，该研究项目的目的是制定一种自适应控制策略，该策略可以有效地用于**在汽车挡风玻璃上运行PETD技术。**
