Closed-loop verification of a compensating group drive model using synthesized formal plant model

Cyber-physical systems are spread among multiple domains of human activity. Their behavior should be strictly validated as most of them are critical. One perspective direction of ensuring system correctness is verification using model checking. A new method for closed-loop model checking of cyber-physical systems has recently been introduced that involves automatic formal plant model synthesis followed by temporal properties verification. The formal model is inferred based on traces gathered from the simulation model. Then, verification of temporal properties for the whole closed-loop system can be performed using the NuSMV tool. The main purpose of this paper is to investigate the applicability of the aforementioned method by performing a case study on the example of a compensating group drive simulation model provided by our industrial partners.
