Description

The Sinusoidal Rotational Velocity Source block produces sinusoidal rotational velocity with a constant offset.

The relative rotational velocity between the base and follower interfaces is

vFB=vFvB,

where:

  • v FB is the relative rotational velocity.

  • vF is the absolute rotational velocity at the follower interface.

  • vB is the absolute rotational velocity at the base interface.

The defining equation for the sinusoidal rotational velocity that the block generates is

v=vo+A*sin(2πft+φ),

where:

  • v is the output rotational velocity.

  • vo is the offset rotational velocity of the output.

  • A is the peak amplitude of the sinusoid.

  • f is frequency of the sinusoid in Hz.

  • t is time.

  • φ is phase shift of the sinusoid.
