Types of Control Systems There are two types of control systems namely:1. Open loop (feedback )2. Closed loop (non-feedback)Open loopIf in a physical system there is no automatic correction of the variation in its output, it is called an open loop control system. That is, in this type of system, sensing of the actual output and comparing of this output (through feedback) with the desired input doesn't take place. The system on its own is not in a position to give the desired output and it cannot take into account the disturbances. In these systems, the changes in output can be corrected only by changing the input manually.These are simple in construction, stable and cost cheap. But these are inaccurate and unreliable. Moreover these systems don't take account of external disturbances that affect the output and they don't initiate corrective actions automatically.Examples of open loop control:1. Automatic washing machine2. Traffic signal3. Home heating (without sensing, feedback and control)Any non-feedback can be considered as a feedback CS if it is under the supervision of someone. Although open loop control systems have economical components and are simple in design, they...more
