Frequency domain $ H_{\infty} $ control design for active suspension systems

<p style='text-indent:20px;'>A methodology for fault-tolerant-control(FTC) is proposed that compensates actuator failures in active suspension systems (ASS). This based on a Frequency Domain approach represents using scale factor to optimize the ASS and improve ride comfort. The controller design carried out off-the-shelf tools linear matrix inequalities (LMIs), guaranteeing asymptotic stability, compensating effect of faults, ensuring certain <inline-formula><tex-math id="M1">\begin{document}$ H_{\infty} $\end{document}</tex-math></inline-formula> performance. In context ASS, performance guarantees correspond comfort presence road disturbances. To validate approach, controllers are developed tested simulation quarter-car model: results illustrate effectiveness approach.</p>
