Mechatronics System Processes
Dynamic
While operating the MS parts interact
dynamically with each other
Showing equifinality
Systems can reach same final
state regardless the initial conditions
and by different ways, in other words
MS are flexible and adapt.
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
Tending to stability
Tendency of the system to stabilize
in ortder to preserve order and control
Codifying the information
Systems react to specific signals
Static
Is when the MS has a
steady state behaviour or
is in dynamic equilibrium
Transformation
Mass, Energy and Information
should turn to products, services,
results, information, etc.
Means
Coordination tasks
How different tasks communicate
and interact with subsystems
Secondary tasks
System elements concentrate
their energy to execute
primary tasks
Primary tasks
Primary regulations or
fundamental tasks
Directedness
Static teleology
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.
