What is cyber physical system (CPS)? Cyber units control physical units. Operating parameters of physical units are sensed by organized sensors Sensed information is communicated with cyber units for real time intervention. Contexts from outside Active model and simulation Main technologies applied Human control Cyber unit Sensor Physical unit System level virtual engineering Intelligent informatics Mathematics in context Representation of behavior Internet of things (IOT) Intelligent sensors Smart control techology Smart assisted human intervention László Horváth UÓ-JNFI-IAM http: //users. nik. uni-obuda. hu/lhorvath/
Engineering Model System (EMS) and its Connections EMS of CPS EA It organizes and relates knowledge contexts for EA model objects during innovation cycle and lifecycle of EA. Contexts from environment Contexts from IP Structure of driving content RFLP structured engineering model System based EA model It uses core elements from Systems Engineering (SE). Physical units IEEE/1220 (1994, 1999, 2005) “Standard for Application and Management of the SE Process”. Cyber units EA production model Sensors Driving contexts with cyber units of CPSs. Cyber units in physically operating CPS EA Engineering is organized around engineering achievement (EA) such as industrial product, prototype, experimental configuration.

Example for cooperating systems Several systems for car driver assistance as example for cooperating systems Adaptive cruise control (ACC) adjusts the speed to maintain safe distance from vehicles ahead. Electronic stability control (ESC) detects when vehicle is not going where the driver is steering. Lane Keeping Assist System (LKAS) counteracts steering torque to keep the centre of the lane. Hill descent control system activates brakes to slow the vehicle, Cooperation between human and systems is a new key area in engineering!

Slm_CS_01 case study Understanding object model and contextual connections in it. Slm_CS_01 case study in active V 6 PLM modeling system. Model in the viewport of the user surface. It serves only communication between human and model generation procedure. While it provides slight information, human may see (synthetize) information which is not in the model. This is a real danger at engineering practice! László Horváth UÓ-JNFI-IAM http: //users. nik. uni-obuda. hu/lhorvath/
