Define a joint-effort residual.
This residual function is defined as \(\mathbf{r}=\mathbf{u}-\mathbf{u}^*\), where \(\mathbf{u},\mathbf{u}^*\in~\mathbb{R}^{nu}\) are the current and reference joint effort inputs, respectively. Note that the dimension of the residual vector is obtained from ActuationModelAbstract::nu
.
Both residual and residual Jacobians are computed analytically.
As described in ResidualModelAbstractTpl(), the residual value and its Jacobians are calculated by calc
and calcDiff
, respectively.
