Phase portraits of Filippov system (3) for Case A11 with different threshold conditions. (a) The boundary equilibrium is globally asymptotically stable, here ; (b) the pseudoequilibrium is globally asymptotically stable, here ; (c) the pseudoequilibrium is globally asymptotically stable, here . The other parameter values are fixed as , , , , , , , , and .
