init(self, tb=0.0, cswitch=False, emin=0.0, k=0.0, te=0.0, emax=0.0, tatb=0.0, rcrfd=0.0, *args, **kw_args)
(Constructor)

Initialises a new 'ExcSCRX' instance.

Parameters:

tb - Denominator time constant of lag-lead block
cswitch - Power source switch: 1 ? fixed voltage 0 ? generator terminal voltage
emin - Minimum field voltage output
k - Gain (> 0.)
te - Time constant of gain block (> 0.)
emax - Maximum field voltage output
tatb - Ta/Tb - gain reduction ratio of lag-lead element
rcrfd - Rc/Rfd - ratio of field discharge resistance to field winding resistance

Overrides: object.__init__
