An LPV/H~~ Active Suspension Control for Global Chassis Technology: Design and Performance Analysis

LPV design of fault-tolerant control for road vehicles

“…An integrated control system is designed in such a way that the effects of a control system on other vehicle functions are taken into consideration in the design process by selecting various performance specifications. Recently, several important papers have been presented on this topic (Yu et al, 2008;Gordon et al, 2003;Palkovics and Fries, 2001;Trachtler, 2004;Zin et al, 2006). This paper proposes a multi-layer supervisory architecture for integrated control systems in road vehicles.…”

A Self Tuning Suspension Controller for Multi-body Quarter Vehicle Model

“…The two degree of freedom control law applied is u = u H∞ (ρ) − c 0żdef , where c 0 can be viewed as the linearized damping coefficient of the controlled damper used for the synthesis and u H∞ , the added energy to achieve the varying performances, obtained by H ∞ synthesis. In (Zin et al, 2006) the c 0 parameter is also used as a varying parameter to change the vehicle behavior. In , this parameter is also used to prevent rollover situations.…”

“…But performances are fixed (Chen and Guo, 2005). Then, LPV control is used either to enforce robustness by scheduling the controller according to measured varying parameters (Zin et al, 2006) or to change the desiderated performances by scheduling the controller objectives using exogenous parameters (Fialho and Balas, 2002;PoussotVassal et al, 2007). Here we aim at synthesizing a controller scheduled according to the deflection level of the nonlinear suspension spring.…”

“…Many suspension control design have been studied in the past few years: Skyhook (Poussot-Vassal et al, 2006), H ∞ (Sammier et al, 2000;, mixed H ∞ /H 2 (Abdellahi et al, 2000;Gáspár et al, 1998;Lu and DePoyster, 2002;Takahashi et al, 1998), LQ (Hrovat, 1997), MPC (Canale et al, 2006) and LPV (Fialho and Balas, 2002;Gáspár et al, 2004;Zin et al, 2006). Most of these controllers are designed and validated using a two degree of freedom nonlinear model that only catches vertical behavior.…”

Fault-tolerant control design for trajectory tracking in driver assistance systems

“…Vassal et al (2011). A global chassis control involving an active suspension and ABS was proposed by Gáspár et al (2010); Zin et al (2008). The driveline system and the brake were integrated in Rajamani et al (2000).…”
