Control Systems Engineering LAB Experiment 5
Experiment 5
Analog Computer (Part 2)
The previous experiment discussed the implementation of a system (differential equations , transfer function, state space model) by op-amps and know the circuits that represent the P-Controller , summer, subtractor and integrators that considered as the basic of analog computer construction.
Analog computer is a collection of op-amps and potentiometers and do all operations that help to implement a system to analyze it.
The construction of the Analog Computer will be covered in the Lab and the tutorial ( Datasheet) of it was attached in the Appendix.
To get the step response of a system you should
-
Implement the system on the analog computer.
-
Connect the output to the oscilloscope.
-
Apply a step input as 1 volt or 10 volt constant.
-
Rescale the graph of the oscilloscope to get a clear view.
Example 1 : Get the step response of H(s) by Analog computer.
Solution :
The previous transfer function H(s) was represented by All integral block diagram as below :
And the op-amp implementations is :
The Analog computer implementation :
Question : Get the step response of
