In the last part, there is a summary of accomplished task, achieved results and a summary of developed concept of inclusion of diagnostic's elements in DAHS that can be used in future to expand the system. Also, the examples was shown, of how the modeling and visualization would work, should those ideas of describing faults be implemented.
Changed diagrams were, in order: "Process characterization", "Processing ways", "Monitoring and analysis" and "Modeling and analysis". Classes corresponding to variable types used in describing fault and diagnostics were implemented as well as relations those classes take part in. It's description was done through editing a domain model of working system. The next part of the thesis was about a concept of inclusion of diagnostic's elements in DAHS system.

Again, the result were confronted with theoretical knowledge about the object in order to determine if the faults were implemented correctly.Ī method to connect the simulator to DAHS with a simulated OPC server was described and effects of that connection were presented as measurement values and set points, originating from simulator, but accessed with the system. Then the simulator was tested with singular faults and their impact on process variables was shown on graphs. Graphs showing the processing variables were analyzed and confronted with theoretical knowledge about the object in order to determine if the simulator was working properly.
The simulator was first tested with no fault, but measurement noise was present. Control over the faults was done by sliders so that it is possible to simulate them as abrupt and do it with different values if need should be. Additive and multiplicative types of faults were taken into account. The faults were chosen based on probability of them occurring as well as their impact on working object. In the next step, faults of the object were developed. Fragments of interface made with use of Simulink Dashboard library were showed to explain the way of setting values within simulator.
Description of the simulator was made by explaining equation corresponding to consecutive elements of the object as well as showing Simulink blocks representing those elements. Included virtual sensors were based on sensors most likely to be found in real object. The first part of the process was focused around developing a simulator of perfect object that works based on equations arisen from laws of physics and accepted conventions, without taking into account any faults.

Designing a simulator of industrial object and developing a concept on how to include diagnostic's elements in DAHSĪbstract The main purpose of this thesis was to design a simulator of industrial process and implement it in Matlab Simulink environment, intended to work with DAHS and develop a conception on how to include diagnostic's elements in DAHS.
