Abstract :
Optimization methods utilizing LQ (linear quadratic) techniques are applied to develop improved motion fidelity of a three-axis motion. The motion simulator (centrifuge) is modeled as a three-axis revolute robot. The optimization procedure is applied to minimize induced accelerations (Coriolis) that commonly occur. Computer simulations of these algorithms demonstrate that over 65% reduction of the untoward accelerations can be obtained
