It would be difficult to deny the importance of optimization in the areas of science and technology. This is in fact, one of the most critical steps in any design process. Even small changes in optimization can improve dramatically upon any process or element within a process. However, determining whether an optimization approach will improve on an original design is usually a question that its...

This paper illustrates the mathematical modeling of passive suspension system and the control strategies for semi active suspension system. The Simulink software developed by Matlab is used to evaluate the control characteristics [1], for the same a 2 DOF quarter car model is used. The comparison and evaluation of control result are made using software-in-the-loop simulation (SILS) method. From...

I. Abstract People daily use their cars for various reasons. This daily traveling also has some disadvantages. For instance, when a car passes a road excitation, the vertical acceleration caused by it may unfavorably affect human health. In this paper, a quarter-car model with semi-active suspension system is considered and three different control approaches (optimal control, fuzzy control, opt...

Abstract This work develops a mathematical model of quarter car suspension system with two degrees freedom and suggests fuzzy adaptive PID controller by assessing the drawbacks conventional control methods. The three parameters are automatically modified control, adjusted in real time. Matlab/Simulink platform is used to create relevant simulation model. results demonstrate superiority suggeste...
