Performance investigation of PID controller in trajectory control of two-link robotic manipulator in medical robots
No full textRobot-assisted surgical procedures have gained much coverage in recent years and favored over manually conducted operations. The medical robots are comprised of manipulators arm that is the multi-degree of freedom positioning devices with a highly non-linear nature to perform various surgical tasks. Due to non-linear effects, robots offer a severe challenge to the control system. Therefore, the control techniques are required for controlling the robots that should be fast enough to accommodate the rapid changes in the system parameters. In this article, the Proportional-Integral-Derivative (PID) controller’s performance has been investigated in trajectory control of the Two-Link Robotic Manipulator (TLRM) for reliable functioning of these robots. Tracking error and Control input factors have been used to investigate the PID controller’s robustness in trajectory control of ‘TLRM.’ Euler’s-lagrange approach has been used for dynamic analysis of ‘TLRM’. This work has been accomplished in the MATLAB®/ Simulink environment.Kuldeep Jayaswal, D. K.

where Rn=Rk ×Rn−k, n>k2 and a point x ∈ Rn is denoted as x=(y, z) ∈ Rk ×Rn−k. As
a consequence we obtain the best constant and extremals of a related Hardy–Sobolev inequality

Moser-Trudinger inequality on conformal discs
No full textWe prove that a sharp Moser–Trudinger inequality holds true on a conformal disc if
and only if the metric is bounded from above by the Poincar ́e metric. We also derive
necessary and sufficient conditions for the validity of a sharp Moser–Trudinger inequality

On-Chip High Impedance RMS Voltage Measurements at 265–300 GHz
No full textFull text access from Treasures at UT Dallas is restricted to current UTD affiliates (use the provided Link to Article).A wideband (265-300 GHz) and high impedance root-mean-square (RMS) detector for on-chip voltage measurements is demonstrated in a 45-nm bulk CMOS process. The detector responsivity is ~70V/W at 10-nA bias. Adding the detector increases the loss of a 140-µm long GCPW thru structure by less than 0.2 dB up to 300 GHz. The compact RMS detectors are placed under a grounded coplanar waveguide feed to a patch antenna with virtually no area penalty, and used to measure the standing wave voltages. The minimum detectable signal of detector is ~37 dBm with a dynamic range of ~40 dB.Erik Jonsson School of Engineering and Computer ScienceTexas Analog Center of Excellenc
