摘要

Under-actuated systems are unavoidable in industrial design applications.Moreover, control problems in dynamic systems require an optimal selection of input trajectories and system parameters.However, it is difficult to find appropriate joint trajectories and system parameters in under-actuated nonlinear dynamic systems.In this study, a method for optimization of the under-actuated open-chain planar robot, and a nonlinear dynamic system is introduced.It simultaneously solves the parameter design problem and the optimal control problem using a specific system state transformation.Also, a novel procedure that optimizes differentially non-flat systems with a good starting point is proposed.It is advantageous when the system has difficulty to obtain convergence due to a small feasible region.Consequently, an example is optimized under various design constraints and the merits of the proposed procedure are discussed. The procedures are performed by the commercial software MATLAB.
