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.
