Cyber-physical agnosticism (CPA) is a property of software in cyber-physical systems (CPS) to withstand various disturbances and keep maintaining the required behaviour of the physical process. With the increased research on the use of internet of things (IoT) in industrial automation (IoT-A), there is a need for robust distributed automation control systems that can take into account some overheads...
This paper presents a novel approach to automation of flexible manufacturing systems with mechatronic intelligence and distributed control. The mechatronic intelligence layer is implemented using a combination of wireless sensor/actuator networks with service-oriented architecture, where services are located at the device level, as well as in local and global Clouds following the Arrowhead framework.
In this paper a speculative computation method for IEC 61499 function block (FB) systems is proposed to increase the level of parallelism when executing the FB system and thus to increase system's performance and to reduce response time on input events. Data and control dependencies in FB systems are recognized and defined as a basis for organizing speculative execution of FB algorithms. A simulation...
In this paper a new modelling approach is presented to be used for formal-verification of block-diagram executable specifications of distributed industrial cyber-physical systems following the IEC 61499 standard. The approach allows usage of timers and arithmetic operations in the controller code. SMV model-checker is used as the target tool. The function block modelswith multiple communicating plant-controller...
This paper proposes an approach to k-bounded Petri nets behavioral equivalence checking using the model checking method and mainstream verifier nuSMV. For the comparison of behavior of two nets, an add-in net is introduced which performs a supervisory control of these two nets. The approach uses an implicit word-to-word comparison of labeled Petri net languages with invisible transitions when computing...
