Active Suspension Design using LPV Control

Nonlinear Optimal Generalized Predictive Functional Control Applied to Quasi-LPV Model of Automotive Electronic Throttle

“…The qLPV system depends upon parameters, the state vector x and the control input u. The matrices A and B are usually nonlinear functions of the scheduling parameter ρ. qLPV systems is when any of the scheduling parmeters ρ are a state of the system [13]. Finally, the components of (11) become:…”

The design of a chassis system based on multi-objective qLPV control

“…According to the dissipative theory, each constraint can be expressed as a supply function, then translated into an LMI (5,9) [9,10].…”

“…The main role of suspensions is to improve comfort by isolating the vehicle chassis to an uneven ground and to provide a good road holding to ensure passenger safety. Suspension control of quarter vehicle have been widely explored the past few years to improve vertical movements either by applying LQ [6], Skyhook [8], H ∞ control [5,12], LPV [4] or mixed synthesis [1,11]. Roll dynamic is catched by the half vehicle model and is directly linked to suspension behaviour.…”

Performance analysis and simulation of a new industrial semi-active damper

“…Suspension control based on quarter vehicle have been widely explored in the past few years to improve vertical movements either by applying Skyhook (Sammier et al, 2003;Choia et al, 2000), H ∞ control (Gaspar et al, 2004) , LPV (Fialho and Balas, 2002) or mixed synthesis (Abdellahi et al, 2000;Takahashi et al, 1998), model-predictive techniques (Canale et al, 2006), using a mix one sensor control strategy (Savaresi and Spelta, 2007). Performance limitations of quarter-car active suspension models have also been studied (Türkay and Akçay, 2007).…”
