“…Due to their widespread applications, for example, in mechanic, viscoelastic systems, dielectric polarization, electromagnetic waves, heat conduction or circuit systems, FO systems have been extensively studied in the past few decades [4][5][6][7]. Particularly, considerable research attention has been devoted to the problems of stability analysis [8][9][10] and controllers design including FO controllers synthesis for IO systems [11][12][13][14][15][16] and state/output feedback controllers synthesis for FO systems [17][18][19][20][21][22]. For example, based on a linear matrix inequalities (LMIs) approach, robust stability and stabilization problems were studied in [23] for FO linear systems with positive real uncertainties.…”
