### Definition of open loop control systems

To introduce closed loop control systems, we first provide a definition of open loop control systems. Systems in which the output value does not affect the input value in the control process are called “open loop control systems”. In these types of systems, no “feedback” is sent from the output to the input and they are called “open systems without feedback” in download free Principle of Control System solution manual written by Bakshi eBook in pdf format .

The purpose of any electrical or electronic control system is to measure, monitor and control a process. One way to have precise control over a process is to monitor the output values ​​and return some of those values ​​to compare the actual output with the desired output to reduce error. If the output fails, the system output can be reset to the desired or desired state in download free Principle of Control System solution manual written by Bakshi eBook in pdf format.

### Definition of closed loop control systems

The measured value of the output is called the “Feedback Signal” and the system that uses the feedback signals to adjust itself is called the “Close-loop System”. A closed-loop control system, or “feedback control system,” is a system that uses the concept of an open-loop system in its forward path, except that it has one or more feedback loops or paths between its output and input. Reference to “feedback” only means that part of the output is returned to the input to create part of the system excitation.

Closed-loop systems are designed to automatically achieve and maintain the desired output by comparing actual conditions with desired conditions. download free Principle of Control System solution manual written by Bakshi eBook in pdf format is done by generating an error signal between the output and the reference input; In other words, a closed-loop system is an all-automated system in which the control operation is in some way dependent on the output. For example, consider an electric clothes dryer (pictured below). Suppose we install a sensor or converter in the system to continuously monitor the temperature or dryness of the clothes and return the output values ​​to the Controller.
