The turning agility of theropod dinosaurs may have been severely limited by the large rotational inertia of their horizontal trunks and tails. Bodies with mass distributed far from the axis of rotation have much greater rotational inertia than bodies with the same mass distributed close to the axis of rotation. In this study, we increased the rotational inertia about the vertical axis of human ...

This paper develops a high dynamic and robust speed-torque control system for servo drives based on adaptive observer and self-tuning techniques with on-line inertia identification. Only the rotor position is measured even for a low precision shaft encoder. The instantaneous speed and the disturbance torque are accurately estimated by an extended Luenberger observer inertia adaptive. A current ...

The virtual synchronous generator (VSG) is a promising way to deal with the lack of physical inertia and damping introduced by power-electronic-based power supply system. However, characteristics may be complicated in paralleled VSG system due stiff grid interactions between control inverters. In this paper, dynamics parallel inverters VSGs studied. equivalent are derived analyzed detail consid...

Single-pole switching scheme is widely used in the Extra High Voltage system. However, the substantial negativesequence current injected to the turbine-generators imposes the electromagnetic (E/M) torque of double systemfrequency components during the dead time (between single-pole clearing and line reclosing). This would induce supersynchronous resonance (SPSR) torque amplifications on low pre...

This paper presents a new application of advanced SMPI controller for newly introduced interconnected dynamic system with VSP based HVDC links frequency control problem. work an outgrowth analysis about the Swarm – Based Optimization Algorithms (SBOAs) in tuning process Multivariable Proportional Integral (MPI) controller, which is called swarm MPI (SMPI). PSO, GOA and GWO algorithms are used d...

This paper addresses the distributed attitude synchronization problem of multiple spacecraft with unknown inertia matrices. Two distributed adaptive controllers are proposed for the cases with and without a virtual leader to which a time-varying reference attitude is assigned. The first controller achieves attitude synchronization for a group of spacecraft with a leaderless communication topolo...
