Hello I do unmanned control for quadrotor helicopter in simulink. I did control algorithm with step change desired trajectory. Now I want make more complex desired trajectories i.e. the helicopter take-off describes a trajectory and returns in starting position. The problem is that I don't know how to describe and program this kind trajectories. If anyone have any ideas how this can happen I would be grateful.

That question is way too general to be answered, so you'll have to elaborate.
If you only want to know how to use more complex signals than a simple step in Simulink, then you should have a look at the Source blocks in the Simulink Library, in particular the From Workspace block.

hi i want control quadrotor with backstepping algorithm in matlab simulation but it dosen't work and give error in Omega_r in t=0 sec ux & uy are unknown parameters for me the paper is:
Backstepping and Sliding-mode Techniques Applied to an Indoor Micro Quadrotor
