To record trajectory tracking performance of a controller, is it resonable to calculate the mean_square_error or the normalized-measn-square-error?

I some papers, the mean square error is considered. In some other, the mse is normalized by dividing the error by the (total sampling instants x the total length of the reference...

Is it reasonable to approximate the quaternion error that is generally represented by the quaternion multiplication by a deduction for small angles?

In page 21 of this lecture note, quaternion error approximation for small errors has been defined as the deduction of the desired from current. It does not make sense mathematically speaking....

What is the general principle of designing the switching control in sliding mode control?

It could be taken as u_sw=-(1/b)ksgn(s) where k is defined as in Applied nonlinear Control by slotine. Does the definition vary for advanced SMC like non-singular terminal SMC?
