Description:What is the automation ?
In the ancient times people worked by hand. They made every tasks, every works without any help. Later they began to do some simple (and later more complicated ) machines, eg. water wheels for lifting water from channels, mills (water and wind mills ) for milling corns, etc. They began to use animals to give their force, their power to get work machines, vehicles, etc.
In the XIXth century the machines were able to do many tasks. Steam engines gave the mechanical energy to machines, but the man had to control every machine.
What does it mean control ? Control consists of some activities:
• observe the phenomena (speed of machine, pressure of steam, temperature of
water, etc.),
• compute (decide) the needed activity (growing or reducing the amount of fuel ),
• set the appropriate device (modify the setting of fuel valves ).
Generally, control has 3 parts: measuring, computing, setting. During evolution machines became more powerful, more quick, more precise, thus human control doesn't fit their tasks. It became necessary to control machines by other machines. This control is the automation. This is the short story of automation.
