Linearization of mass spring damper system for applying linear control PID techniques

Abstract

This paper describes a basic experiment about linearization of a second order system as a mass spring damper structure, the mathematical model of system is obtained with characteristics of physical components, the linearization of system is made with acquired signal of a no lineal sensor and getting a new lineal equation, for validation of process a simulation with all components is made. In implementation PID controller process analog electronic components are used. The results show a correct performance when an external disturbance is added to system using the PID controller. Also several test are made changing the reference point, the simulation results show a good performance of controller.
