A list of top frequently asked Control System interview questions and answers are given below. When the number of elements connected performs a specific function then the group of elements is said to constitute a system or interconnection of various components for a specific task is called system. Example: Automobile. Any set of mechanical or electronic devices that manages, regulates or commands the behavior of the system using control loop is called the Control System. It can range from a small controlling device to a large industrial controlling device which is used for controlling processes or machines.

For open control system which of the following statements is incorrect? A control system in which the control action is somehow dependent on the output is known as a Closed loop system b Semiclosed loop system c Open system d None of the above Ans: a. In closed loop control system, with positive value of feedback gain the overall gain of the system will a decrease b increase c be unaffected d any of the above Ans: a. Which of the following is an open loop control system? Which of the following statements is not necessarily correct for open control system? In open loop system a the control action depends on the size of the system b the control action depends on system variables c the control action depends on the input signal d the control action is independent of the output Ans: d.
