Input Shaper in Simulink

I'm doing a research for my final year which is related to a anti-sway controller for a 3D crane system by using Input shaping techniques, so I wonder how can we make a Input shaper by using Simulink's blocks? How do we convolve initial command with input shaper to generate shaped command? I'd tried with Pulse generator block, buffer block and convolution block in Simulink but it didn't work.
