I want control the displacement with many displacement point.
How can i do in opensees？
Thanks.
Can I control the displacement with (0->+3->-5->+7-

not quite sure what you mean.
if you mean DisplacementControl with a different nodal increment at each step, just do something like:
foreach nodalIncr { 3 -8 2 4} {
integrator displacementControl node? dof? $nodalIncr
analyze 1
}
don't make the steps too big, you might want to do a number of steps; i.e.
integrator displacementControl node? dof? [expr $nodalIncr/10.0]
analyze 10
if you want to specify the displacement at boundaries in the model, i.e. imposed displacement, use load patterns of type MultiSupport.

If i have the data of displacement test.
The first since 0 increase until 6.67 , than decrease until -3.32.
The second since -3.32 increase until 8.19, than decrease until -7.58.
The last since -7.58 increase until 21.05, than decrease until -17.2.
