According to the actual q-axis current and the actual position signal,

angular acceleration and angular velocity are obtained by the Luenberger observer.

Herein, the evaluation indexes are selected as half-car body center vertical displacement acceleration transmissibility ([T.sub.g]), sprung mass vertical displacement acceleration transmissibility ([T.sub.sf], [T.sub.sr]) and dynamic travel transmissibility ([T.sub.df], [T.sub.dr]) of the front and rear quarter-car suspensions, and Root-Mean-Square (RMS) of the half-car body pitch

angular acceleration (a0); the calculation method is given in [7].

The sensor market for

angular acceleration sensors is very small.

Mesurement of Newton's constant using a torsion balance with

angular acceleration feedback.

Calculation of

Angular Acceleration Using Savitzky-Golay Filter.

The

angular acceleration, angular velocity of attack and the angle of attack for the distal part of the fin;

This is also supported by Figure 6, where reference tracking of a ramp signal from 0 to 80 rad/s with

angular acceleration [[epsilon].sub.ref] = 1066.6 rad/[s.sup.2] is shown.

1 represents angle of rotation, second graph angular velocity and last graph

angular acceleration. Angular velocity was obtained derivation of rotation angle and

angular acceleration derivation of angular velocity.

where [M.sub.m], [M.sub.r] are the reduced driving moment and the reduced moment of resistance forces; [epsilon], [omega], [phi] are the

angular acceleration, angular velocity, and rotation angle of the reduction link; [J.sub.R] is the reduced mass moment of inertia of the mechanism that is calculated according to (***, 2010).

The physical effect of this imballance is represented by a momentary bending and

angular acceleration of the rocket frame, due to the inherent dissymetry of the aerodynamic loads along the frame (Fig.

Modeling a dancer as an inverted pendulum and assuming no adjustments to correct for imbalance are made, there is an inverse relationship between the

angular acceleration away from equilibrium and the effective pendulum length, [l.sub.eff] [[??] =(g / [l.sub.eff]) sin [theta]].
