Applied Mechatronics: Designing a Sliding Mode Controller for Active Suspension System

The suspension system is referred to as the set of springs, shock absorbers, and linkages that connect car wheel system. main purpose provide comfort for passengers, which created by reducing effects road bumpiness. It worth noting such vibrations also diminishes noise undesirable sound well fatigue on mechanical parts vehicle. Due importance abovementioned issues, objective this article reduce implementing an active control method For purpose, a conventional first-order sliding mode controller has been designed stochastic quarter-car model. noteworthy significant ability overcome effects, uncertainty, deal with nonlinear factors. To design controller, governing dynamical equation presented considering terms in springs absorber, taking into account uncertainty factors actuator. process its stability investigated Lyapunov stability. In current research, surface variations are considered Gaussian white noise. behavior controlled uncontrolled situations simulated extracted results have presented. Besides, existing actuator evaluated robustness checked. Also, obtained quantitative qualitative compressions Moreover, effect parameters basin attraction extensiveness assessed. achieved indicated good performance stabilize mitigate bumpiness presence
