Trajectory Planning for Point-to-Point Motion Using High-order Polynomials

In this paper, a trajectory planning problem based on high-order polynomials is formulated for a point-to-point motion. The problem aims to find suitable polynomial trajectories that connect an initial to a final configuration while satisfying other specified constraints. The constraints are considered as zero velocity at the endpoint as well as a limitation on acceleration […]

Backstepping Predictive Direct Power Control of Grid-Connected Photovoltaic System Considering Power Quality Issue

In this paper, a grid connected PV system acting as shunt active power filter for power quality enhancement is presented. Further, a DC-DC boost converter is used to interface the photovoltaic generator with the grid, which provides a continuous power flow from the PV generator into the grid through a Voltage Source Inverter (VSI). Hence, […]

Design of a 16-by-16-bit Unsigned Serial-parallel Multiplier using Retime Technique

In this paper, the structure of a 16-by-16 unsigned hybrid (serial-parallel) multiplier has been proposed. Parallel multipliers, in comparison with serial multipliers, have higher speed and higher power consumption. In hybrid structures, to reduce power and increase speed, both serial and parallel techniques are used. The proposed structure improves propagation delay and reduces power consumption […]
