Title: Open and Closed-Loop Control Systems - (Motor speed). I. Objectives. The object of this experiment is to investigate the principles of open and closed-loop control of a rotating body using a speed sensor and a d.c. tachogenerator to provide feedback There is also the ability to use m-file syntax directly in. LabVIEW through the After the closed-loop model is constructed, you should simulate the unit disturbance response and the unit set-point In the next section, you will build a model of the open-loop system for the process mentioned earlier and determine the unit Types of control systems. There are two types of control systems namely: 1. Open loop control systems (non-feedback control systems). 2. Closed loop control systems (feedback control systems). Open loop control system. If in a physical system there is no automatic correction of the variation in its output, it is called an open Closed-loop feedback control system (with feedback). Controller. Measurement. Process.
