This paper presents the digital PI control method for design and simulation of a high precision limited angle brushless torque motor control system in Field Programmable Gate Array device (FPGA). The direct drive structures which are widely applied in many servo control fields. Matlab Xilinx System GeneratorR toolbox based on Fixed-Point Arithmetic is used to design the digital PI controller using DSP architecture
plot the responses of the control system and generate the VHDL source code. The control system model consists of a digital PI
a real LABTM
and a real absolute Inductosyn
encoder to rpm and position blocks. Through loading generated codes in process of the simulation that built by the digital discrete model
it is verified that the rising time of current loop is only 1.2ms
and rate loop is 8ms
overshoot is rarely 4.2%. Finally
the comprehensive positioning accuracy of system can reach up to 5 arc sec
and the rate jitter achieves 5% with the 4 arc sec accuracy absolute Inductosyn. (2013) Trans Tech Publications

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.

A high-performance robust controller of permanent-magnet synchronous motor (PMSM) drive with cascade linear auto disturbance rejection controller (LADRC) is proposed. The robust controller combines the simplicity of linear controller and the merit of the auto disturbance rejection controller (ADRC). First
a systematic mathematical model is derived according to the required specifications for the PMSM drive system. Then
for the model
this paper designs the controller that includes three first-order LADRCs. The controller does not rely on the accurate mathematical model of motor. The controller can estimate and compensate the disturbances that include load disturbance and systematic parameters changes by the linear extended state observer (LESO). Simulation results show that compared with conventional PI controller
the proposed approach has strong robustness. In the same load disturbance
the speed fluctuation of the LADRCs accounts for 30% of PI controller. 2011 IEEE.

CCD noises and their causes are analyzed. Methods to control these noises
such as Correlated Double Sampling (CDS)
filtering
cooling
clamping
and calibration are proposed. To improve CCD sensor's performances
the IC
called Analog Front End (AFE)
integration of CDS
clamping
Programmable Gain Amplifier (PGA)
offset
and ADC
which can fulfill the CDS and analog-to-digital conversion
is employed to process the output signal of CCD. Based on the noise control approaches
the idea of chip design of linear CCD drive pulse generator and control interface is introduced. The chip designed is playing the role of (1) drive pulse generator
for both CCD and AFE
and (2) interface
helping to analysis and transfer control command and status information between MCU controller and drive pulse generator
or between global control unit in the chip and CCD/AFE. There are 6 function blocks in the chip designed
such as clock generator for CCD and AFE
MCU interface
AFE serial interface
output interface
CCD antiblooming parameter register and global control logic unit. These functions are implemented in a CPLD chip
Xilinx XC2C256-6-VQ100
with 20MHz pixel frequency
and 16-bit high resolution. This chip with the AFE can eliminate CCD noise largely and improve the SNR of CCD camera. At last
the design result is presented.
