Smooth and time-optimal trajectory planning for industrial manipulators along specified paths
TL;DR: In this paper, a method for determining smooth and time-optimal path constrained trajectories for robotic manipulators is presented, where the desired smoothness of the trajectory is imposed through limits on the torque rates.
Smooth and time-optimal trajectory planning for industrial manipulators along specified paths
TL;DR: The experimental results presented show that the planned smooth trajectories provide superior feasible time-optimal motion.
Journal ArticleDOI
Haptic rendering of rigid contacts using impulsive and penalty forces
TL;DR: A new simulation approach is proposed to improve the stability and the perceived rigidity of contacts during haptic interaction with multirigid body virtual environments by derived impulsive forces using a new multiple collision resolution method that never increases the kinetic energy of the system.
Journal ArticleDOI
Distributed model predictive control of constrained weakly coupled nonlinear systems
TL;DR: The paper shows that, for a given bound on the disturbances, the recursive feasibility is guaranteed if the sampling interval is properly chosen and establishes sufficient conditions for the overall system state to converge to a robust positively invariant set.
Journal ArticleDOI
A describing function technique for multiple nonlinearities in a single-loop feedback system
TL;DR: In this paper, a graphical technique for determining the existence of limit cycles, their amplitude, frequency, and stability when they exist, and the stability of a single-loop feedback system with n - 1 memoryless nonlinear elements and one nonlinear element with memory is considered.
