Semester V (Section A / B) Control System Lab. CASE, Islamabad. 3 Experiment # 5 . Objectives : 1.Types of Experimental Data. 2.Transient Response. 3.Determining the model from Time-Response Data. Theory: There are several reasons for using experimental data to obtain a model of the dynamic system to be controlled. In the first place, the best theoretical model build from equations of motion is still only an approximation of reality. Sometimes, as in the case of a very rigid spacecraft, the theoretical model is extremely good. Other times, as with many chemical processes such as papermaking or metalworking, the theoretical model is very approximate. In every case, before the final control design is done, it is important and prudent to verify the theoretical model with experimental data. Secondly, in situations where the theoretical model is especially complicated or the physics of the process is poorly Control System Lab....
