Positioning Control of a Shell Transfer Manipulator under Uncertain via a Piecewise Linear Control Algorithm
The accurate positioning control of a novel shell transfer manipulator with vibration base is studied in this paper.Firstly,the working principle of the manipulator is expounded and the dynamic model of the manipulator is built via the Lagrange of the second kind.Secondly,on the assumption that the control force is bounded in norm,a feedback controller is designed,based on a piecewise linear control algorithm.The controllers gains changed as a step-function of time,while the system approaching the terminal state.The control force always satisfies the given constrain.Finally,the dynamic equation is solved using Runge-Kutta method.Results demonstrate that the controller greatly compensates the effects of the external perturbation,fulfills the accurate point to point control of the shell transfer manipulator,and has good robustness.
