Angular velocity

View this topic in
In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed of an object and the axis about which the object is rotating. The SI unit of angular velocity is radians per second, although it may be measured in other units such as degrees per second, revolutions per second, revolutions per minute, degrees per hour, etc. (Wikipedia.org)

  • Experimental demonstration of an optical centrifuge for molecules

    Summary form only given. Strong field molecular optics aims to control the position, velocity and acceleration, as well as the alignment, angular velocity and angular acceleration of a molecule. Molecular optics shares position control with atomic optics and optical tweezers. Rotation and dissociation are a distinctly molecular processes. Our experiments demonstrate that an extremely strong torque can be applied to a molecule, accelerating it to rotational energy sufficient to break it by the centrifugal force in just 50 ps. The physics on which the molecular centrifuge is based is the angle dependent Stark shift. For small molecules the well depth can exceed 50 meV. That is, even room temperature molecules can be trapped. Adiabatically rotating the laser polarization must rotate the trapped molecule. Accelerating the rotation of the laser polarization must accelerate the molecular rotation. We have studied three different molecules, Cl/sub 2/, O/sub 2/ and CS/sub 2/ with most work performed on Cl/sub 2/.

  • Analysis of steering control in vehicles with two independent left and right traction wheels

    Based on the kinematic studies of motion for a vehicle equipped with a pair of motorized wheels which, by having appropriate velocities, can provide traction forces as well as steering action, a steering control strategy is derived. The angular velocities for the right and left wheels are considered, the two control inputs which cause a system to follow a desired trajectory. Assuming these inputs to be linear functions of the two errors associated with path tracking problem (position and orientation errors), through an appropriate Lyapunov function, a control policy is determined. The path tracking behaviour of a mobile robot using such a control law is demonstrated by computer simulation.<<ETX>>

  • Torsional delayed resonator with velocity feedback

    This paper concerns a vibration absorption scheme, which is called the delayed resonator (DR). Torsional vibration cases are considered here for the first time with the new scheme. The angular velocity which is a commonly measurable state for rotating systems, is fed back with a controlled time delay, as opposed to the position and acceleration of the earlier studied translational vibration cases, some interesting distinctions of this control law are highlighted. Analytical and experimental findings are presented to show how the method of DR absorption can be adapted on an electric drive setting. The stability analysis is also reviewed for the entire system, including the DR absorber and the original oscillatory structure. Encouraging agreement between analytical and experimental findings are reported.

  • Time Scale Analysis of a Digital Flight Control System

    In this paper, we consider the fifth order discrete model of an aircraft (longitudinal) control system which possesses three slow (velocity, pitch angle and altitude) and two fast (angle of attack and pitch angular velocity) modes and exhibits a two-time scale property. Using the recent results of the time scale analysis of discrete control systems, the high-order discrete model is decoupled into low-order slow and fast subsystems. The results of the decoupled system are found to be in excellent agreement with those of the original system.

  • On global feedback stabilization of the angular velocity of a rigid body

    V. Andriano (Systems & Control Letters, vol. 20, p. 361-4, 1993) proved a result on global stabilizability of the angular velocity equations of a symmetric rigid body. The aim of this paper is to show that a simpler proof can be given for a general version of the result.<<ETX>>

  • Centrifugal compressor surge and speed control

    Previous work on stabilization of compressor surge is extended to include control of the angular velocity of the compressor. A low-order centrifugal compressor model is presented, where the states are mass flow, pressure rise, and rotational speed of the spool. Energy transfer considerations are used to develop a compressor characteristic. In order to stabilize equilibria to the left of the surge line, a close coupled valve is used in series with the compressor. Controllers for the valve pressure drop and spool speed are derived. Semiglobal exponential stability is proved using a Lyapunov argument.

  • Further passivity results for the attitude control problem

    In this paper we establish passivity for the system which describes the attitude motion of a rigid body in terms of minimal three-dimensional kinematic parameters. In particular, we show that linear asymptotically stabilizing controllers and control laws without angular velocity measurements follow naturally from these passivity properties. The results of this paper extend similar results for the case of the (nonminimal) Euler parameters.

  • Attitude Tracking With Adaptive Rejection of Rate Gyro Disturbances

    The classical attitude control problem for a rigid body is revisited under the assumption that measurements of the angular rates obtained by means of rate gyros are corrupted by harmonic disturbances, a setup of importance in several aerospace applications. This note extends previous methods developed to compensate bias in angular rate measurements by accounting for a more general class of disturbances, and by allowing uncertainty in the inertial parameters. By resorting to adaptive observers designed on the basis of the internal model principle, it is shown how converging estimates of the angular velocity can be used effectively in a passivity-based controller yielding global convergence within the chosen parametrization of the group of rotations. Since a persistence of excitation condition is not required for the convergence of the state estimates, only an upper bound on the number of distinct harmonic components of the disturbance is needed for the applicability of the method.
