STUDYING OF OPEN LOOP CONTROLLER ON DRIVE SYSTEM

A control system is an interconnection of components shaping a system configuration that will give the required system response. The basis for analysis of a system is the foundation provided by a linear system, which assumes a cause - effect relationship between the components of a system. An open - loop control system uses a controller to gain the desired response. The open - loop control system is used to control the process by an input signal direct ly without taking benefits of feedback. The open - loop system does not use feedback to determine if the output has achieved the desired target of the input. Hence, the system will not observe the output of the processes that it is controlling. As a result, an open - loop system would not correct any errors that it would happen. The objective of this laboratory procedure was to measure and investigate certain parameters and characteristics about an open loop, alternating current (AC) motor drive system .
