The objective of this work was to design, build and control a second-order mass-spring system in order to make it useful for studies in the area of control, mechanics and vibration systems. In the initial phase of this project,  i contributes to the dimensioning of the mechanical structure, dimensioning of actuators and also in the control circuit. Later, together with my co-worker, we model and control the system through the application of controller design techniques by analises of root locus.
