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

$$v_{FB}=v_F-v_B,$$

where:

• v _FB is the relative rotational velocity.

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

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

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

$$v=v_o+A*\sin (2\pi ft+\phi ),$$

where:

• v is the output rotational velocity.

• v_o 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.
