Detailed Description

Dome-regulator model. Z_reg(s) is a high-pass: ~0 below the corner (regulated), -> Z_hf above
(regulator can't keep up). Z_hf = 0 means the regulator is NOT MODELLED: the feed sees an ideal
pressure source, which is what a dome regulator plus ullage is at the ~100 Hz chug band. The
forcing bound ``max_excursion_pa`` is reported, NOT used in the characteristic equation.  [Phys §6.1]

impedance()

complex engine.pipeline.stability.chug.Regulator.impedance	(		self,
		complex	s )

Series impedance Z_reg(s) [Pa·s/kg]. High-pass toward Z_hf above the corner.

Definition at line 54 of file chug.py.

modelled()

bool engine.pipeline.stability.chug.Regulator.modelled

(

self

)

True only when the regulator can change the loop: enabled AND a measured Z_hf.
