【Abstract】 On the basis of singular perturbation theory, a composite control approach is proposed for constrained flexible manipulators. The dynamic equation of a constrained twolink flexible manipulator is divided into a slowsubsystem and a fastsubsystem. Based on the adaptive theory, the slow controller is designed. For the fast subsystem, a robust optimal controller is presented. Under the slow time scale and the fast time scale, a composite control strategy is constructed. Some results of numerical simulations are presented to show the effectiveness of this design procedure.更多还原
