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.**

除冰或除霜透明的挡风玻璃在许多应用中是一个关键的操作问题，如汽车、飞机、机车和海上船只。由于环境条件、挡风玻璃几何形状和车速等影响结霜的可变**参数，这些应用中的除冰过程消耗了大量的时间和能量。脉冲电热除冰(PETD)技术是一种可以在很短的时间内高效除冰的有利方法。PETD技术利用强大的电脉冲，导致霜层和挡风玻璃之间接触面的冰层融化。预置控制器不会提供优质的效率，可能需要最终用户手动**调整，因为PETD技术的效率取决于许多可变参数，如**室外温度、霜冻类型和厚度、挡风玻璃几何形状和倾斜度以及电力供应。因此，需要**自适应控制方法来调制必要的输出参数，如脉冲功率、频率、占空比**和基于可变输入参数的分布。这种自适应控制单元应该实时测量这些外部**参数，并通过内部控制算法运行它们，以便提供最佳的输出参数，以达到最佳的**效率。因此，本研究项目的目标是开发一种能够有效地用于**在汽车挡风玻璃上操作PETD技术的自适应控制策略。
