Topic: Self-sensing Control of AC Drives at Very Low and Zero Speed

Abstract:

The elimination of rotor position/velocity sensors (and cabling) in AC drives has long been desired, the methods developed to achieve this goal are commonly referred to as sensorelss control. Among the expected benefits of sensorless control are cost and size reduction, as well as increased robustness.

Sensorless control techniques for AC machines that rely on the fundamental excitation are capable of providing high performance control in the medium- to high-speed range, but fail in the very low-speed range and/or for position control. Sensorless methods based on tracking the position of saliencies (asymmetries), measure the response of the machine when high-frequency excitation, which is superimposed to the fundamental excitation used for torque production, is applied. These methods have the capability of providing position/speed control in the low-speed range, including zero speed.

Furthermore, the use of the information embedded in the high frequency signals offers interesting opportunities for the online monitoring of machine condition, eventually contributing to increase the reliability of the drive

Topic: Traction Electric Drives: Encoderless Operation and Active Thermal Control

Abstract:
One of the promising types of electrical machines is DC excited synchronous motor. Recently only Renault used this machine in traction, and now BMW had introduced a new powertrain for the iX3 car. DC excited motors enable utilization of the traction motor as a rotary transformer replacing position encoder, which previously was a mandatory part of electrical traction machine. Synchronous homopolar motor is a machine with brushless DC excitation having a number of benefits in traction. The operation principle, equations, and sensorless control strategies for this motor will be introduced. The thermocycling problem is relevant to the traction electric drive, and the active thermal control helps to improve situation. The open-end winding topology of the traction motor will be considered as a promising solution enabling both fault-tolerant operation and thermal stabilization of the semiconducting devices regardless of the operation speed and mission profile.

Topic: Fault Tolerance Potential of Multiphase Electric Traction Drives

Abstract:
The electrification of vehicles and their autonomous operation is a current topic. The resulting high requirements on reliability for safety-critical applications leads to the need of fault tolerance in order to provide fail-operational modes. One possibility to increase fault tolerance of electric traction drives is increasing the number of phases of the machine, since a performance degradation is possible while using multiple phases. The advantages of multiphase systems, the comparison of different phase numbers, and methods for an evaluation at an early stage will be presented within this keynote speech. It is shown that a higher phase number is not always the best choice regarding fault tolerance and reliability. This fact is depending on the performance demand after failure required in order to assure a fail-operational mode. Additionally to the increase of the phase number, the use of multilevel inverter topologies and of an electric energy source in matrix topologies (for fuel cells or batteries) is auspicious regarding the system’s fault tolerance. Furthermore, some applications of the methods and the respective results will be presented from former research projects.

Topic: Possibility of Digital Twins Technology for Improving Reliability of the Electric Drive

Abstract:
A modern trend for industry digitalization brings new demands for the development and application of the modeling and simulation approach. It is already not enough to have only a virtual representation of the object and run it independently from the physical object. The Digital Twin aspect indicates a connection between the physical object and the corresponding virtual twin established by generating real-time data using physical and virtual sensors. The DT represents physical object operation throughout its life cycle, making it an essential tool for improving that object’s reliability. It is not necessary to run Digital Twin always in real-time, it can be used to test out hypothetical scenarios for maintenance, diagnostics, “what if?” analysis and risk assessment. Reduced models of the physical entities for Digital Twins can be constructed using different model order reduction methods. A variety of condition monitoring techniques are available nowadays and may be combined with Digital Twin approaches, e.g. electromagnetic field monitoring, noise and vibration monitoring, infrared recognition, temperature measurements, radio frequency emission monitoring, chemical analysis, acoustic noise measurement, motor current signature analysis (MCSA) and most advanced artificial intelligence-based techniques, such as fuzzy logic and neural networks etc.

Topic: Single Chip Design of mixed critical and high reliability motion systems with ZYNQ Ultrascale+

Abstract:

Integration of components with high performance, high reliability and different levels of criticality onto a common hardware platform is becoming an outstanding requirement for the motion industry. Availability of new embedded devices integrating heterogeneous architectures with multi-core clusters, many cores with real-time capability and programmable logic is enabling design and implementation of mixed criticality system (MCS) the motion market. Reliability and safety plays a lion’s share in supporting the often hostile environment where motion systems are working. A plethora of standards the IEC 61508, ISO13849, IEC 62061, and EN 61800-5-2 are foundational for motion systems, and in addition to safety and reliability principles they require a large amount of other disciplines to harmonize mission critical (the drive and Motion PLC), safety critical, low criticality and scheduling for worst case execution time (WCET). Xilinx achieved successfully the qualification according to IEC61508 Annex E SIL3 and HFT = 1 for its ZYNQ Ultrascale+ single chip, making it possible to design motion systems fulfilling the new criticality requirements. The recent advancement of machine learning has opened the possibility of increasing the overall reliability of the entire machine not only the motion system using fault prediction. This talk explains the architectures, the certification elements of the single chip, the partition between many-core, multi-core, and programmable logic to address the different level of safety and criticality on single chip. The software implications with hypervisors, WCET, diagnostic, and security requirements are presented as well for realizing certified motion system needed by the industry today. The talk includes also elements of predictive maintenance using machine learning to provide a complete system.
