Modelling and control of four and six DOF active engine mount system using (PID and LQR)

Abstract

In this paper, classical and modern controllers have been introduced on three different engine models starting form a moderately realistic four degree of freedom model and then a realistic six degree of freedom model, two control techniques were implemented on the different systems namely proportional integral derivative (PID) and linear quadratic regulator (LQR), respectively then comparison was done between their simulation results and performance assessment for the controllers simulation results was conducted and showed a significant enhancement in isolating the vibrations of the engine from the car body.
