某天，你班贴出了一张通知，请根据通知，内容要点和要求写一篇英语发言稿。

The main content of this thesis is as follows: 1The structures of EPS are analyzed. The main components of EPS are introduced in detail. Then the distributed torque in EPS is analyzed and the control system model is set up. 2Three control modes are discussed and the control strategy of EPS is studied in detail. Three principal modules in the control strategy are discussed—the predicted module which predicts motor rotational speed and steering rotational speed, the power-assistant module and the return control module. 3The assistant torque curves of the motor are designed by using the B-spline, so that any kind of custom-built assistant torque curves can be designed according to different kinds of automobiles. 4The hardware frame of EPS is studied. The developed controller based on 8-bit MCU MC68HC908MR8 is introduced and many related circuit units are designed, including the control circuit, the driver control circuit and so on. The software structure is discussed, then the steering control program flowchart is given.

本文的主要工作有： 1分析了EPS 的总体构成，对EPS 的各个部件作了详细的介绍，并在此基础上分析了EPS 的受力情况，建立了控制系统模型，并研究了EPS 的安全性能； 2讨论了EPS 的三种控制方式，提出了控制策略，并讨论了其中三个关键模块的作用：预估模块包括对电机转速和方向盘角速度的预估，助力控制模块以及回正模块； 3用B 样条插值方法进行EPS 助力曲线的设计，可按照用户的要求设计任意形状的助力曲线，以满足不同车型和不同用户的要求； 4研究了控制系统的硬件结构，以MC68HC908MR8 为核心设计了控制器，详细讨论了控制器的控制电路、驱动电路等；设计了控制系统的软件，给出了控制程序流程图，并对要点进行了详细的说明。
