◆ compute()

const ConstraintBase & tsid::tasks::TaskJointPosVelAccBounds::compute	(	const double	t,
		ConstRefVector	q,
		ConstRefVector	v,
		Data &	data
	)

virtual

Implements tsid::tasks::TaskBase.

◆ computeAccLimits()

void tsid::tasks::TaskJointPosVelAccBounds::computeAccLimits	(	ConstRefVector	q,
		ConstRefVector	dq,
		bool	verbose = `true`
	)

Given the current position and velocity, the bounds of position, velocity and acceleration and the control time step, compute the bounds of the acceleration such that all the bounds are respected at the next time step and can be respected in the future. ddqMax is the absolute maximum acceleration.

Definition at line 369 of file src/tasks/task-joint-posVelAcc-bounds.cpp.

◆ computeAccLimitsFromPosLimits()

void tsid::tasks::TaskJointPosVelAccBounds::computeAccLimitsFromViability	(	ConstRefVector	q,
		ConstRefVector	dq,
		bool	verbose = `true`
	)

Compute acceleration limits imposed by viability. ddqMax is the maximum acceleration that will be necessary to stop the joint before hitting the position limits.

-sqrt( 2*ddqMax*(q-qMin) ) < dq[t+1] < sqrt( 2*ddqMax*(qMax-q) ) ddqMin[2] = (-sqrt(max(0.0, 2*MAX_ACC*(q[i]+DT*dq[i]-qMin))) - dq[i])/DT; ddqMax[2] = (sqrt(max(0.0, 2*MAX_ACC*(qMax-q[i]-DT*dq[i]))) - dq[i])/DT;
