主 题:Impedance control lower limb rehabilitation robots model predictive compensator optimal predictive impedance controller optimization in the presence of uncertainty
摘 要:As an innovative concept,an optimal predictive impedance controlle is introduced here to control a lower limb rehabilitation robo in the presence of *** desired impedance law is considered to propose a conventional model-based impedance controller for the ***,external disturbances,model imperfection,and parameters uncertainties reduce the performance of the controller in *** order to cope with these uncertainties,an optimal predictive compensator is introduced as a solution for a proposed convex optimization problem,which is performed on a forward finite-length *** a result,the LLRR has the desired behavior even in an uncertain *** performance and efficiency of the proposed controller are verified by the simulation results.
