Fault diagnosis of mechanical systems based on electrical supply characteristics
This thesis examines the effectiveness of both motor current and voltage signals using spectrum analysis for detecting broken rotor bar and shaft misalignment and gear oil viscosity changes with different degrees of severities under sensorless control (close) modes.
Angular Position Control of Permanent Magnet Synchronous Motor Using Compensation of the Nonlinearities of the DQ-Model
- Engineering2018 IEEE XXV International Conference on Electronics, Electrical Engineering and Computing (INTERCON)
Simulation results prove the accuracy and robustness of the proposed angular position controller and the design of the controller becomes easier.
Design Optimization of Modern Machine-drive Systems for Maximum Fault Tolerant and Optimal Operation
Position control of PMSM based on augmented Fuzzy Takagi-Sugeno SISO models and LMIs
- EngineeringIECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society
The addition of the integrator and the independent position and d-axis stator current models allows more flexibility in the placement of the closed-loop local model poles, in order to control the dynamic behavior of the PMSM.
Effect of Number of Inputs on Designing Fuzzy Logic Controllers
It has been proven that fuzzy controllers are capable of controlling non-linear systems where it is cumbersome to develop conventional controllers based on mathematical modeling. This chapter…
Simplified Estimation of Stator Flux of Induction Motor for Direct Torque Control using SPLINE
- Engineering2019 IEEE XXVI International Conference on Electronics, Electrical Engineering and Computing (INTERCON)
Direct torque control (DTC) allows having a speed and torque control with good dynamic response. However, DTC uses a square root function to get the motor stator flux. This function is difficult to…
The analysis of power supply signals by including phase effects for machine fault diagnosis
Experimental evaluations have found that these two proposed methods allow common faults in the downstream gearbox including gear tooth breakage, oil shortage and excessive bearing clearances to be detected and diagnosed under high load conditions, showing the effectiveness and accuracy of these two new approaches.
