Modeling\ experimental validation and parameter optimisation constitute the three vital
phases in the design of dynamic systems[ High cost of the design e}orts related to modeling
and experimental validation of dynamic systems can be justi_ed if the implementation of
an optimisation process...
In earlier publications\ the authors have presented modeling and experimental validation
results of suspension dynamics of front load horizontal!axis washing machines[ In this
paper\ various formulations for suspension design optimisation are discussed and
implemented using grid and sequential...
Presented solution can significantly improve learning
experience of PLC programming with minimal funds.
Instead of building complex and expensive models,
software simulation can and should be used. This approach
has many pros and these are just some of them:
• easier to develop,
• cheaper to...
After programming the PLC, before starting a real
process, the operator has to verify if the program is
correct, i.e. if the PLC correctly performs the predefined
control task. Therefore, the operator monitors the states at
input and output port of the PLC. A usual way is to
monitor all the...
It is very important to monitor and test the
operation of Programmable Logic Controller (PLC) in real
time (online). There are many conventional, but expensive
monitoring systems for PLC, such as Supervisory Control
and Data Acquisition (SCADA) systems, software and
hardware simulators (or...
This doc. describes the design considerations
of microcontroller based process control for washing machine.
In this paper, AT89S51 microcontroller is used to control the
process of washing cycle and to drive the external output
devices such as water inlet valve, wash motor, water drain
