Figure 6

Phase portraits of Filippov system (3) for Case with different threshold conditions. (a) The regular equilibrium is globally asymptotically stable, here ; (b) the pseudoequilibrium is globally asymptotically stable, here ; (c) the regular equilibrium is globally asymptotically stable, here . Parameter values are , , and , and other parameters are chosen as shown in Figure 5.
