摘要
Time-optimal controls for 2-link robots are often of bang-bang type. Many algorithms to solve time-optimal robot control problems a-priori assume the optimal control to be bang-bang. Industrial robots very often have. 5 or 6 links and then the associated time-optimal controls are usually singular. This paper presents a new algorithm that enables computation of both bang-bang and singular time-optimal controls for robots. The algorithm uses both the conjugent gradient and Gauss-Newton method to enhance its efficiency and does not require state-parameterization I,, which introduces additional errors. The algorithm is used to compute time-optimal controls for an industrial 5 link robot model including gravity and viscous friction.
