Mechatronics key elements part 2

SIMULATION:
Simulation is the process of solving the model and is preformed on a computer
The process of simulation can be divided into 3 sectors:
  • Initialization
  • Iteration
  • Termination or display  
If the starting point is a block diagram based  model description
In initialization section the equation for each of the block must be sorted according to hte pattern in which the blocks have been connected

Iteration section:  The iteration section solves any differential equation present in the model using numerical integration or differentiation

Display section:    the display section of a simulation is used to present and past process the output . output may be saved to file displayed as a digital reading or graphically displayed as a chart strip chart meter read out or even animation

Automatic control:  control is a general term and can occur in living beings as well as machines . The term automatic control describes the simulation in which a machine is controlled by another machine.
Control involves modification of a system behavior, a transfer function is used to represent a control system
The transfer function is the ratio of the output variable to the input variable

One of the crucial ingredient of automatic control is feed back.
It provides the mechanism for attenuating the effects of parameters variations and disturbances .
