Riassunto analitico
We presented a method for obtaining numerical solutions of optimal control<br>problems (OCP) for systems of ordinary differential equations with possible appli-<br>cations in dynamic tasks in combination with predictive control algorithms based<br>on the model. The method is intended for applications that require the resolution<br>of OCP in a short time and can efficiently exploit the prior knowledge ( obtained<br>for example by the application of the Principle of Maximum) of control’s arcs by<br>determining their length and sequence.<br>The presented method has been applied in simulation and to a real prototype<br>of planar robotic manipulator with two degrees of freedom with elastic joints.<br>Experimentally it was obtained that the system in the tested configuration is<br>able to reach a speed higher than double that attainable without elastic joints .<br>The approach with predictive control enables a reduction of the error on the desired<br>final pose of the robot up to 10 times compared to about an experiment conducted<br>with control in open loop.
