Adaptive PI Controller Design to Control a Mass-Damper-Spring Process

Abstract

In this paper, the authors have applied adaptive control to a mass damper spring. During the whole design process, only parametric disturbances have been considered. Based on the uncertainty parameters (mass, damping constant, and spring) and by using a gradient method (the MIT rule), a PI adaptive controller is proposed and designed. The used gradient method (i.e. the MIT rule) allowed for the studied parameters to be varied in a predefined range. The whole design, as well as the experimental results, was done in Matlab/Simulink.
