High-performance control methods for demanding electric drive systems.
Christian Vorobev works on the conception, development, and commissioning of stator-fixed control methods for high-performance electric drives. The aim is the best possible utilisation of existing resources in the drive system. The focus is on scientifically grounded methods for efficiency, dynamics, system utilisation, and practical integrability. His work connects research on electric machines and power-electronic systems with practical experience in modelling, firmware development, and commissioning.
Value
Technical perspectives
Every drive application involves a trade-off between cost, material input, energy efficiency, and performance. Suitable control methods shift these trade-offs: they can make better use of existing hardware, reduce losses, and unlock dynamic reserves without requiring the system to be dimensioned larger than necessary.
Cost and material
Potential for equal performance with reduced material, installation-space, or component requirements.
Integration
Control methods with attention to practical integrability, commissioning, and system-level implementation.
Topics
Making better use of existing drive systems
The Topics page shows how more can be extracted from an existing machine and inverter through new control approaches: both efficiency and power limits can be increased by single- to double-digit percentages while keeping the material input of inverter and machine unchanged. The resulting power and efficiency advantages translate almost directly into increased margins. The methodological core is model-based, stator-fixed control with optional synchronous pulse patterns. Commissioning remains simple when sufficient modelling is available.
