Detailed Description

template<typename _Scalar>
class crocoddyl::ResidualModelCoMPositionTpl< _Scalar >

CoM position residual.

This residual function defines the CoM tracking as \(\mathbf{r}=\mathbf{c}-\mathbf{c}^*\), where \(\mathbf{c},\mathbf{c}^*\in~\mathbb{R}^3\) are the current and reference CoM position, respectively. Note that the dimension of the residual vector is obtained from 3. Furthermore, the Jacobians of the residual function are computed analytically.

As described in ResidualModelAbstractTpl(), the residual value and its Jacobians are calculated by calc and calcDiff, respectively.

Constructor & Destructor Documentation

◆ ResidualModelCoMPositionTpl() [1/2]

ResidualModelCoMPositionTpl	(	std::shared_ptr< StateMultibody >	state,
		const Vector3s &	cref,
		const std::size_t	nu
	)

Initialize the CoM position residual model.

Parameters

[in]	state	State of the multibody system
[in]	cref	Reference CoM position
[in]	nu	Dimension of the control vector

◆ ResidualModelCoMPositionTpl() [2/2]

ResidualModelCoMPositionTpl	(	std::shared_ptr< StateMultibody >	state,
		const Vector3s &	cref
	)

Initialize the CoM position residual model.

The default nu value is obtained from StateAbstractTpl::get_nv().

Parameters

[in]	state	State of the multibody system
[in]	cref	Reference CoM position

Member Function Documentation

◆ calc()

virtual void calc	(	const std::shared_ptr< ResidualDataAbstract > &	data,
		const Eigen::Ref< const VectorXs > &	x,
		const Eigen::Ref< const VectorXs > &	u
	)

virtual

Compute the CoM position residual.

Parameters

[in]	data	CoM position residual data
[in]	x	State point \(\mathbf{x}\in\mathbb{R}^{ndx}\)
[in]	u	Control input \(\mathbf{u}\in\mathbb{R}^{nu}\)

Reimplemented from ResidualModelAbstractTpl< _Scalar >.

◆ calcDiff()

virtual void calcDiff	(	const std::shared_ptr< ResidualDataAbstract > &	data,
		const Eigen::Ref< const VectorXs > &	x,
		const Eigen::Ref< const VectorXs > &	u
	)

virtual

Compute the derivatives of the CoM position residual.

Parameters

[in]	data	CoM position residual data
[in]	x	State point \(\mathbf{x}\in\mathbb{R}^{ndx}\)
[in]	u	Control input \(\mathbf{u}\in\mathbb{R}^{nu}\)

Reimplemented from ResidualModelAbstractTpl< _Scalar >.

◆ createData()

virtual std::shared_ptr<ResidualDataAbstract> createData ( DataCollectorAbstract *const data )

virtual

Create the residual data.

The default data contains objects to store the values of the residual vector and their Jacobians. However, it is possible to specialize this function if we need to create additional data, for instance, to avoid dynamic memory allocation.

Parameters

data	Data collector

Returns: the residual data

Reimplemented from ResidualModelAbstractTpl< _Scalar >.

◆ print()

virtual void print ( std::ostream & os ) const

virtual

Print relevant information of the com-position residual.

Parameters

[out] os Output stream object

Reimplemented from ResidualModelAbstractTpl< _Scalar >.
