Hello arunkumar,

Good question.

Process control is the addition of valves and temperature gauges (to name one of many) that you create to control the process. An example is that you have the computer automatically fill up a batch tank to 500 gallons and then shut the valve that supplies the water.

Process control can be implemented in a simulation or in real-life.

Process modeling and simulation is an imitation of the real thing. http://en.wikipedia.org/wiki/Simulation

I hope this helps,
