A geometrical interpretation of current transient responses to predict current gradients for IPMSM model predictive cont...
The ability to use actuator and load models online in combination with experimental data becomes increasingly important in future electrical drives. Amongst the applications of such online model in torque and flux controllers, model predictive control (MPC) has gained increasing interest, allowing to deal in real time and in a suboptimal way with d...
Active demagnetization fault compensation for axial flux permanent-magnet synchronous machines using an analytical inver...
In this article, a fault tolerant deadbeat controller is proposed, which is able to compensate for both partial and uniform demagnetization faults in axial flux permanent-magnet synchronous machines with double rotor, even with asymmetric defects in both rotors. For this purpose, the system model used by the deadbeat controller is equipped with a l...
Motion control of biohybrid microbots under low Reynolds number environment: Magnetotaxis
Biohybrid microbots with small body size, have been integrated successfully into miniaturized system/process with confined geometry and/or closed environments. One such specific case is the construction of microbot, composed of microswimmer with other functional nanomaterials that allow non-conventional taxis-based strategy to guide the motion of t...

Giant flagellins form thick flagellar filaments in two species of marine gamma-proteobacteria
Flagella, the primary means of motility in bacteria, are helical filaments that function as microscopic propellers composed of thousands of copies of the protein flagellin. Here, we show that many bacteria encode “giant” flagellins, greater than a thousand amino acids in length, and that two species that encode giant flagellins, the marine γ-proteo...
Interturn Short Fault Diagnosis in a PMSM by Voltage and Current Residual Analysis With the Faulty Winding Model
As interturn short fault (ISF) in a permanent-magnet synchronous machine (PMSM) degrades its energy efficiency and may cause other problems, accurate fault diagnosis for the PMSMs is necessary. In this paper, we present a method that uses voltage and current residual components to diagnose the phase and the severity of the ISF in PMSMs. A faulty-wi...
Light-Guided Nanomotor Systems for Autonomous Photothermal Cancer Therapy
Machines have greatly contributed to the human civilization, enabling tasks beyond our capacities for improved quality of life. Recently, the progress in nanotechnology has triggered to build a miniaturized machine of nanoscale. In this context, synthetic nanomotors have gained considerable interest because of their great promise for diverse applic...
Adaptive Torque Estimation for an IPMSM with Cross-Coupling and Parameter Variations
This paper presents a new adaptive torque estimation algorithm for an interior permanent magnet synchronous motor (IPMSM) with parameter variations and cross-coupling between d- and q-axis dynamics. All cross-coupled, time-varying, or uncertain terms that are not part of the nominal flux equations are included in two equivalent mutual inductances, ...
Analytical model for combined study of magnet demagnetization and eccentricity defects in axial flux permanent magnet sy...
A time-harmonic analytical model is presented for a combined study of demagnetization and rotor eccentricity in single-statordouble-rotor axial flux permanent magnet synchronous machines (AFPMSM). Demagnetization defects are modeled by scaling the magnetization "square wave" by magnetization factors for each individual magnet on both rotors. Static...
