ContinuousClock

Generates a continuous time signal that starts counting from a specified time.

A clock component that outputs a continuously increasing signal starting from a specified time. The output equals the offset value until the simulation time reaches start_time, after which it increases linearly with time. The output value is calculated as offset + (time - start_time) when time exceeds start_time, otherwise it remains at the offset value.

This component extends from Signal

Usage

BlockComponents.ContinuousClock(start_time=0.0, offset=0.0)

Parameters:

Name	Description	Units	Default value
start_time	Time at which the signal starts changing from its offset value	s	0
offset	Constant value added to the signal output	–	0

Connectors

• y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

$$\begin{array}{rl}y\left(t\right)& =ifelse(\mathtt{start}\mathtt{\_}\mathtt{time}<t,\mathtt{offset}-\mathtt{start}\mathtt{\_}\mathtt{time}+t,\mathtt{offset})\end{array}$$
