Maybe a stupid question (Read 2955 times)

Ciprian New Member Offline Posts: 2	Maybe a stupid question Aug 18^th, 2014, 6:58am Maybe is a stupid question as the subject says. Can anyone explain me the role of Theta and Tau functions and what they do? analog begin �V(vp, vn) <+ Km*Theta(shaft) + RmI(vp, vn) + ddt(LmI(vp, vn)); �Tau(shaft) <+ KfI(vp, vn) - DTheta(shaft) - ddt(j*Theta(shaft)); end

Ciprian,
please check the discipline.vams file.
Mine reads Code:

... // Conservative disciplines
discipline rotational
	potential � �Angle;
	flow � � � � Angular_Force;
enddiscipline

discipline rotational_omega
	potential � �Angular_Velocity;
	flow � � � � Angular_Force;
enddiscipline

It also defines Theta and Tau.
