Method Detail

numConstraints

public int numConstraints(int qpsize)

Returns the number of constraints associated with this term.

Parameters:

qpsize - size of the quadratic program. For the tracking controller, this is the number of excitation values being used,

getTerm

public int getTerm(MatrixNd A,
                   VectorNd b,
                   int rowoff,
                   double t0,
                   double t1)

Appends the constraints for this term to the constraint matrix A and offset vector b. For inequality constraints, A and b define the constraints

 A x >= b
 

while for equality constraints, they define the constraints

 A x = b.
 

Parameters:

A - quadratic program constraint matrix

b - quadratic program offset vector

rowoff - row offset within A and b where the constraints should be added

t0 - time at start of step

t1 - time at end of step
