power_init - Set initial state values of model built with Simulink and SimPowerSystems software

Syntax

[x0,states] = power_init(sys)
[x0,states] = power_init(sys,'look')
power_init(sys,'states')
power_init(sys,'ForceToZero')
power_init(sys,'ResetToDefault')
power_init(sys,'x0',x0)
power_init(sys,'look')
power_init(sys,'reset')
power_init(sys,'steady')

Description

Power_init deals with two types of state variables: the Simulink State variables and the Electrical State variables. The Simulink States consists of the entire set of state variables of a model (including the Electrical states) seen by Simulink software. The Electrical States are the particular Simulink states that defines the capacitor initial voltages and inductor initial currents of the SimPowerSystems blocks of your model.

[x0,states] = power_init(sys) returns the initial states values and state names of your model.

[x0,states] = power_init(sys,'look') returns the electrical initial states values and state names of sys.

power_init(sys,'states') displays in a two-column format the initial state values and names of your model.

power_init(sys,'ForceToZero') sets to zero the initial states your model. It uses the Data import/export initial state option of the Simulink Configuration Parameters menu to specify the initial state values. Use the ResetToDefault option of power_init to reset the Simulink configuration parameters to its previous settings.

power_init(sys,'ResetToDefault') resets the initial state of Simulink configuration parameters to the settings prior to the use of the ForceToZero option of power_init. This option has no effect on system if the ForceToZero option is not used before.

power_init(sys,'x0',x0) sets the initial state values equal to the vector specified by x0. The ordering of the states variables is given by the state option of power_init. This option uses the Data import/export initial state option of the Simulink Configuration Parameters menu to specify the initial state values.

power_init(sys,'look') displays in a two-column format the electrical initial states names and values of your model.

power_init(sys,'reset')resets the electrical initial states of sys to zero.

power_init(sys,'steady') sets the electrical initial states of sys to simulate the electrical circuit in thesteady state.
