Description

This model represents a power continuous storage element. The element has a preferred flow out causality. The corresponding constitutive equations then contain an integration. The element can also have the non-preferred effort out causality. The constitutive equations then contain a derivation.

 

flow out causality (preferred):

 

state = int(p.e) + state(0);

p.f = state/i;

output = state;

 

effort out causality:

 

state = i*p.f;

p.e = d state / dt;

output = state;

Interface

Ports

Description

p

Input port of the storage element.

Causality

 

preferred flow out

An effort out causality results in a derivative constitutive equation.

Outputs

 

output

The output signal is equal to the state.

Parameters

 

i

The storage element constant.

Initial Values

 

state(0)

The initial value of the storage element.
