Data for: An ontology-based approach to knowledge representation for Computer-Aided Control System Design
The ontology consists of a knowledge model about the design of lead-lag controllers by the root locus method. The ontology was built grounded on the underlying mathematical concepts (numbers, quotients, polynomials, roots, etc). On top of these concepts, the ones pertaining to the language of control engineering were defined. Then, by combining or applying restrictions to these basic concepts, more complex ones were represented. Finally, with all this network of interrelated concepts, the ones guiding the design process could also be built. There are two ontologies: 1. Cekb is the basic ontology. It has 258 clases and 810 instances. 2. filled_cekb is the ontology after executing an example of root locus design. It has nearly 40.000 instances.
