| 520 | |a The automobile industry has developed significantly through years, and producing fuel efficient cars became the most important priority for automobile manufacturers and that will affect the cars weight to make them lighter using composites and alloys that is lighter than steel and have a better strength to weight ratio and therefore have a low fuel consumption and by utilizing efficient engine mounts powerful engines can be installed into light vehicles yet such mounts are seldom and the introduction of more powerful engines to lighter cars will cause more vibrations that will not likely be damped by the traditional mounts specifically the low frequency vibrations and that will affect the passengers comfort and health in order to remedy this quagmire active engine mounts were introduced the typical active engine mount consists of a rubber passive mount and a force actuator that will be activated at certain frequencies and generate a damping force approximately equal to the disturbance force, thus these systems will reduce the amount of vibrations that reaches the passenger cabin more than the passive and semi active engine mount systems, many control techniques has been investigated in order to enhance the performance of the active mounting, yet most of the control techniques has been implemented on unrealistic models and it is seldom to find any realistic model of active engine mount. In this dissertation classical and modern controllers has been introduced on three different models starting form two degree of freedom unrealistic model and then a moderately realistic four degree of freedom model and finally a realistic six degree of freedom model, two control techniques were implemented on the different systems namely (PID) proportional integral derivative, (LQR) linear quadratic regulator, 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 . | ||
