Non-linear MPC for winding loss optimised torque control of anisotropic PMSM

The Journal of Engineering, 2019
For a non-linear anisotropic permanent magnet synchronous machine (PMSM), a prediction model for model predictive control (MPC) considering effects like cross-coupling and saturation is developed in a straight forward procedure.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Performance enhancement of PMSM using a hybridizing of nonlinear backstepping control and an optimized linear quadratic regulator

Energy Exploration & Exploitation
An important characteristic of permanent magnet synchronous machines is that they are extremely efficient due to the absence of rotor losses, such as in induction motors, and the use of permanent magnets for field excitation.
