Assessment of DC servo motor with sliding mode control approach

Abstract

This paper contracts with the specific type of robust control i.e., sliding mode control for position and speed controlling of a DC servo motor. The paper contributes synthesis and investigation of DC servo motor with sliding mode controller and conventional PI controller. Modeling and simulations are carried out and their enactment is assessed in steady as well as in transient state. Subsequently the DC servo motor drive is sensitive to parameter variation and load disturbance, a robust control methodology based on sliding mode is comprehended. The planned sliding mode controller results are compared with conventional PI controller with no load and on load condition. The usefulness of the projected methodology is demonstrated by performing simulations using MATLAB tool. The simulation results exhibit that the role of sliding mode based scheme is more robust than fixed gain controller.
