Optimal trajectories for flexible-link manipulator slewing using recursive quadratic programming: Experimental verification

Experimental verification of minimum time, straight-line tracking using a two-link planar flexible robot is presented. Previously reported minimum-time angle histories are precompensated to account for joint servo-actuator dynamics. Using the precompensated joint commands, the optimal joint angles are tracked with such fidelity that the tip tracking error is less than 1.8 percent of the tip travel distance
