CPE4.0 for intelligent drive technology
The “Cognitive Power Electronics 4.0” (CPE4.0) concept developed at Fraunhofer IISB aims to combine proven power electronics with data analytics and machine learning to enable intelligent digital functionalities from the power electronics level to the system level and to optimize associated value chains.
In the lead project “CPE4.0 for intelligent drive technology”, this approach is transferred to the broad field of electrical drive technology. The motivation for this is to collect critical operating states and faults in the electric motor in real time using information from the drive inverter, to classify them automatically and, if possible, to predict them (predictive analytics).
There are specific requirements for (dynamic) drive technology with regard to the necessary modifications of the hardware and application-specific developments in the field of algorithms. The focus of the research work is on the necessary functional extensions of drive inverters and the utilization of the electrical parameters of the inverter for predictive analysis in real time.
The electric drive thus ultimately becomes an integrated intelligent system that can provide information about its current and future operating status and can also (re-)act autonomously.
