What do you know about control systems?

An interviewer might ask "What do you know about control systems?" to a/an Electrical Design Engineer to gain insight into the Engineer's understanding of how to design systems that meet desired objectives while accounting for constraints. This is important because designing effective control systems is critical to the success of many engineering projects.

Example: “A control system is a system that regulates the behavior of other systems or processes. Control systems are used in a variety of applications, including mechanical systems (e.g., robots), manufacturing processes (e.g., assembly lines), and social systems (e.g., traffic control). In each of these examples, the goal of the control system is to ensure that the system or process behaves in a desired manner.

There are two main types of control systems: feedback control systems and feedforward control systems. Feedback control systems use feedback from the system being controlled to adjust the inputs to the system. Feedforward control systems do not use feedback from the system being controlled; instead, they use information about the desired behavior of the system to directly set the inputs to the system.

Both feedback and feedforward control systems can be either open-loop or closed-loop. An open-loop control system does not use feedback from the system being controlled; instead, it relies on a predetermined relationship between the inputs and outputs of the system. A closed-loop control system uses feedback from the system being controlled to adjust its inputs accordingly.

The most common type of feedback control system is a PID controller. PID controllers use Proportional, Integral, and”
