Drift angle is a transverse intersection angle of vector of image motion of the space camera. 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.

To improve the automatic detection efficiency of photoelectric encoder
an auto-detection system of photoelectric encoder is designed using DSP (TMS320F2812) as the core device. A 21-bit high accuracy photoelectric encoder is used as the angle standard. It is connected to the detected photoelectric encoder coaxially. They will rotate synchronously under the driving of electric motor. Data acquisition and processing system collects the angular data of the two photoelectric encoders at the same angular position and calculates the angular error of detected photoelectric encoder. Then the data is put into computer. The computer will display the data error. The result of experiment shows that the system could detect encoder whose bit-number below 19
the detecting person could be reduced to one and the detecting speed could be increased to 8-10 times. 2010 IEEE.

By summarizing the corresponding parameters Of the driving system of a 4-m Alt-azimuth telescope
some unit techniques like the driving modes and structure
angular position measurement methods in detail
have been analyzed in the paper. A set of primary schemes for astronomical applications
including the altitude axes being driven by 2 DC torque motors
the azimuth by 4 DC torque motors using helical gears
and two pieces of the 27-bit segment tape encoders for each set of axes is proposed. To meet practical engineering needs
the shafting motion parameters are designed and motor elementary parameters are primarily calculated to offer the important references for further study on system driving model and prototype development.
