Control engineering

Control engineering is the engineering discipline that focuses on mathematical modeling of systems of a diverse nature, analyzing their dynamic behavior, and using control theory to create a controller that will cause the systems to behave in a desired manner. Modern control engineering is closely related to electrical, electronic and computer engineering, as electronic circuits can often be easily described using control theory techniques. And also it is related to biological sensor. Control engineering needs Electrical circuits, digital signal processors and microcontrollers. As engineering is developing, control engineering is often desired. For example, there are automobile, biologcal engineering, wireless communication, and etc.
