A nonlinear output feedback controller is developed for an Underactuated manipulator in this paper. The PPR planar Underactuated manipulator consists of two active joints and one passive joint. The dynamic constraint on the free link is 2nd-order non-holonomic. Firstly, the motion equations are transformed into a special form using some global coordinate and input transformations. Secondly, a time-varying...
The development of safe and dependable robots for physical human-robot interaction requires both the mechanical design of lightweight and compliant manipulators and the definition of motion control laws that allow compliant behavior in reaction to possible collisions, while preserving accuracy and performance during the motion in the free space. For these motivations, great attention has been posed...
This paper addresses the issue of trajectory tracking control based on a neural network controller for industrial manipulators. A new control scheme is proposed based on neural network technology and linear feedback approach for tracking a planned trajectory. The control system is established with two parallel subsystems designed separately. One is a linear controller based on state feedback with...
