Abstract

In this paper the main aim is to stabilize the Triple Link Inverted Pendulum (TLIP) system on a cart. The mathematical model and state space dynamics of the TLIP system is discussed. The TLIP system is inherently unstable, so a Linear Quadratic l Regulator Design (with a degree of stability) is presented. The stability, controllability, and observability are investigated. The choice of weighting matrices in LQR is also discussed. Then an Observer-based controller is designed for the TLIP system. The simulation is done with MATLAB environment and a comparative study of the time domain characteristics are shown.

Keywords
