fracpid

PURPOSE

FRACPID Create a new fractional-order PID controller in parallel form.

SYNOPSIS

function [pidCtrl, ctrlType, ltxString] = fracpid(varargin)

DESCRIPTION

FRACPID Create a new fractional-order PID controller in parallel form.

        A parallel form of the fractional-order PID controller is assumed,
        i.e. Gc(s) = Kp + Ki/s^lambda + Kd * s^mu.

   Usage: [PIDCTRL, CTRLTYPE] = FRACPID(KP, KI, LAMBDA, KD, MU)
           CTRLTYPE will contain a string with controller type.
   Note: no parameter may be omitted! Pass Ki and/or Kd = 0 with any lambda
         and mu to obtain various controller types (P, PI, PD, PID).
