Mechatronics System Processes

Static

Is when the MS has a
steady state behaviour or
is in dynamic equilibrium

The enviorment, limit, input and output.

Everything outside the MS limit
is the enviorment and for preserving
order and control the MS should be
connected with it.
The Enviorment must provide inputs,
accept outputs and provide feedback
to the MS, therefore this interactions
MS-Enviorment is fundamental.

Limit

Physical

Material and structural

Temporary

Operating time and expected life

Social

Ergonomic characteristics

Psychological

Appearance and operating way

Inputs

Mass

Energy

Information

Outputs

Mass

Energy

Information

Product, Services, Information,etc

Transformation

Mass, Energy and Information
should turn to products, services,
results, information, etc.

Means

Primary tasks

Primary regulations or
fundamental tasks

Static teleology

Directedness

Secondary tasks

System elements concentrate
their energy to execute
primary tasks

Coordination tasks

How different tasks communicate
and interact with subsystems

Dynamic

While operating the MS parts interact
dynamically with each other

Codifying the information

Systems react to specific signals

Tending to stability

Tendency of the system to stabilize
in ortder to preserve order and control

Tending to disorder

The physical systems tend to disorder,
the MS must correct or stop the process
of disorganization to conserve order and
control during its life

Showing equifinality

Systems can reach same final
state regardless the initial conditions
and by different ways, in other words
MS are flexible and adapt.
