Information
In a fifth step, a filter is added for the highPressureTurbine to avoid the implicit nonlinear
equation and instead solve it using a “pseudo” controller. Note that the filter also requires
suitable start values. The controller time constant should be chosen sufficiently small so as not to
interfere with the pressure ramp. The parameter startTime = -1 allows the system to reach
a steady state before time = 0.
Further documentation is available in the JouleBrayton package.
