The motion of space manipulator with a flexible base will generate interaction forces and torques acting at the base, which cannot be avoided. In order to improve the control performance of the manipulator and the vibration depressing effect of the flexible base, a kind of combined control law is proposed. That is, a resolved acceleration control considering base information is adopted during path...
This paper presents a new CMOS current-feedback operational amplifier based on the adoption of the MOS tube in order to improve slew-rate. The cascode circuit was used to decrease the influence of power supply. Resistance feedback was used in the output stage to improve its load driving capability. Simulation results of the CFOA using BSM3's 0.25um CMOS process parameters with PSPICE, result in a...
With the development of network technology and the increasing popularity of the network, the Internet Word-of-Mouth is gradually replacing its traditional counterpart. People increasingly prefer to collect product information using the network exchange in order to make consumption decisions. Involvement theory plays an important role in the theory of consumer behavior; it explains why people sometimes...
To meet the needs of the log curves vectorization, roller scanner can be used to acquire geophysical log images. However, skews are inevitably introduced during the process of long image scanning. Skew correction is an important step to obtain precise digital log curves. Grid lines in log curves can be applied as the basis for skew detection. The arrangement of both depth line and scale line is analyzed...
