PDE Control of Vehicle-mounted Flexible Link with Input Saturation and Disturbances

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A boundary and distributed control of a movable vehicle-mounted flexible link carrying a payload depicted by partial differential equations (PDEs) is considered. A disturbance observer is carried out and controllers are designed to trace positions of joint and vehicle simultaneously with input constraints. In addition, elastic deformation of robot link is also eliminated by adopting proposed control laws. Then candidate Lyapunov functions are constructed and asymptotic stability of the closed-loop system is proved using extended LaSalle's invariance principle (LIP). Finally, control performance of the closed-loop system is verified by numerical simulations.
