Abstract: | Based on nonlinear trajectory generation (NTG) software package, a general approach (i.e. numerical solution) to trajectory
planning for yoyo motion is presented. For the real-time control of such periodical dynamic system, a critical problem is
how to implement fast solving the optimal trajectory, so as to meet the real-time demand. However, traditional numerical solution
methods are very time-consuming. In this paper, the optimization problem is solved by mapping the problem to a lower-dimension
space. And combined with multithread programming technology, the computation time for solving the optimal trajectory is greatly
reduced. Simulation results show that the numerical solution is identical to the analytic one, which demonstrates the correctness
of the proposed method. The computation time of one cycle of yoyo simulation is about 10 ms, which shows that the proposed
numerical method can be applied to the real-time control of yoyo playing. |
