We analyze a bubble forming system composed of particles with competing longrange repulsive and short range attractive interactions driven over aquasi-one-dimensional periodic substrate. We find various pinned and slidingphases as a function of substrate strength and drive amplitude. When thesubstrate is weak, a pinned bubble phase appears that depins elastically into asliding bubble lattice. For stronger substrates, we find anisotropic bubbles,disordered bubbles, and stripe phases. Plastic depinning occurs via the hoppingof individual particles from one bubble to the next in a pinned bubble lattice,and as the drive increases, there is a transition to a state where all of thebubbles are moving but are continuously shedding and absorbing individualparticles. This is followed at high drives by a moving bubble lattice in whichthe particles can no longer escape their individual bubbles. The transitionbetween the plastic and elastic sliding phases can be detected via signaturesin the velocity-force curves, differential conductivity, and noise. When thebubbles shrink due to an increase in the attractive interaction term, they fitbetter inside the pinning troughs and become more strongly pinned, leading to areentrant pinning phase. For weaker attractive terms, the size of the bubblesbecomes greater than the width of the pinning troughs and the depinning becomeselastic with a reduced depinning threshold.
