modelCISESim2States
CISE plant reduced model with boundary conditions and initial steady-state computation
Information
This model provides the boundary condition values to the CISEPlant2Statesmodel; it can be used to simulate open-loop transients.
The steady state is obtained by setting the derivatives of all the state variables to zero in the initial equation section. The offset values for ValveOpening1 and wfeed1, i.e. the parameters ValveOpening_offset and wfeed_offset have a fixed=false attribute. Their actual values are set by the two additional initial equations specifying the initial drum level and pressure.
The CISESim2States120501 model extends CISESim2States by adding suitable numerical values to the boundary condition signal generators.
