Time Optimal Control of Flexible Systems Subject to Friction Authors Kim J-J., Kased, R., & Singh, T. Source 2004 AIAA Guidance, Navigation and Control Conference Abstract This paper presents a technique for the determination of timeoptimal control profiles for a rest-to-rest maneuvering multiple spring-mass-damper system, subject to Coulomb friction. A parameterization of the control input which accounts for the friction force, resulting in a linear analysis of the system is proposed. Optimality condition are examined for the control profile resulting from the parameter optimization problem. The variation of the optimal control structure as a function of final displacement is exemplified on the friction benchmark problem. |
