Abstract
In this paper, an electromechanical mass lifter system is designed,
analyzed and compare using optimal
and robust control theories. LQR and μ -synthesis controllers are
used to improve the lift displacement by
comparison method for tracking the desired step and sinusoidal wave
signals input. Finally, the comparison
simulation result prove the effectiveness of the electromechanical
mass lifter system with μ -synthesis controller for
improving the rise time, percentage overshoot, settling time and peak
value of tracking the desired step displacement
signal and improving the peak value for tracking the desired sinusoidal
displacement signal with a good
performance.
