This　paper　investigates　the　boundary　feedback　control　for　the　two-lane　traffic　flow　with　lane-changing　interactions　in　the　presence　of　actuator　saturations.　The　macroscopic　traffic　dynamics　are　described　by　the　Lighthill-Whitham-Richards　(LWR)　model　for　both　two　lanes.　Two　variable　speed　limits　(VSLs)　are　applied　at　boundaries　for　controlling　the　vehicle　velocity　so　as　to　stabilize　the　traffic　density　of　each　lane.　A　saturated　boundary　feedback　controller　is　proposed　to　drive　the　traffic　densities　of　both　lanes　to　the　steady　states.　In　contrast　to　the　fruitful　results　in　saturated　control　of　ordinary　differential　equation　(ODE)　systems,　there　are　few　related　studies　for　hyperbolic　partial　differential　equation　(PDE)　systems.　We　define　the　exponential　stability　for　the　hyperbolic　PDEs　under　saturated　control.　Then　sufficient　conditions　for　ensuring　exponential　stability　of　the　two-lane　traffic　flow　system　are　developed　in　terms　of　matrix　inequalities　under　both　the　linear　and　nonlinear　cases,　by　employing　the　Lyapunov　function　method　along　with　a　sector　condition　in　L2-norm　and　H2-norm,　respectively.　Finally,　the　effectiveness　of　the　proposed　conditions　is　validated　by　numerical　simulations.　©　2022　IEEE.
