Hello Dhanashree!
It totally depends on your interest. Scope of electronic control system are give below :
Control and automation have a lot of potential in a rapidly growing country like India. Today, there are huge plants for conventional sources of energy, steel, oil and gas which have opened a plethora of opportunities for Electronics Control Systems Engineers. The objective of systems engineers is to increase the efficiency of these plants by reducing the output cost. The thrust being laid on clean energy and the focus being on harnessing renewables, the demand for Electronics Control Systems Engineers will increase in the utilities, distribution companies, and the independent power producers who would be hiring them. Their role acquires significance as they would have to keep a tab on the grid which will see an influx from the conventional as well as non-conventional source of energy.
Hope this answer helps.
Good luck...
