    FO lead/lag compensators are equivalent to band-limited FO PI/PD controllers implemented in a specific frequency range $(\omega_b,\omega_h)$. You can tune these in FOMCON.

    dear alekesi
    how to approximate(implement) fractional order [PI]lamda and fractional order [PD]mu controller.
    please let me know
    thanks in advance

    E.g., using the Oustaloup approximation method.
