Adjusting the angle could reduce the influence on image quality. Ultrasonic motor (USM) is a new type of actuator using ultrasonic wave stimulated by piezoelectric ceramics. They have many advantages in comparison with conventional electromagnetic motors. In this paper  some improvement was designed for control system of drift adjusting mechanism. Based on ultrasonic motor T-60 was designed the drift adjusting system  which is composed of the drift adjusting mechanical frame  the ultrasonic motor  the driver of Ultrasonic Motor  the photoelectric encoder and the drift adjusting controller. The TMS320F28335 DSP was adopted as the calculation and control processor  photoelectric encoder was used as sensor of position closed loop system and the voltage driving circuit designed as generator of ultrasonic wave. It was built the mathematic model of drive circuit of the ultrasonic motor T-60 using matlab modules. In order to verify the validity of the drift adjusting system  was introduced the source of the disturbance  and made simulation analysis. It designed the control systems of motor drive for drift adjusting system with the improved PID control. The drift angle adjusting system has such advantages as the small space  simple configuration  high position control precision  fine repeatability  self locking property and low powers. It showed that the system could accomplish the mission of drift angle adjusting excellent. 2011 SPIE.   Performance analysis and stability control for multireach canals 期刊论文 2010, 2010 Shang Yizi; Wu Baosheng 收藏  |  浏览/下载：54/0 Design and implement of detecting module for mid-infrared laser power density measurement 期刊论文 2010, 2010 Yang Peng-ling; Feng Guo-bin; Wang Qun-shu; Yan, Y.; Cheng Jian-ping 收藏  |  浏览/下载：4/0 Adaptive mode method in inverse dynamics of a rotating flexible manipulator with high-frequency excitation 期刊论文 2010, 2010 Li Qing; Wang Tianshu 收藏  |  浏览/下载：3/0 Adaptive Kriging model for NO/sub x/ emissions from utility boilers 期刊论文 2010, 2010 Kong Liang; Ding Yanjun; Zhang Yi; Wu Hao; Zhang Xue; Wu Zhansong 收藏  |  浏览/下载：3/0 无传感器交流传动技术的展望 期刊论文 2010, 2010 J.Holtz; 梅杨; J.
