Experimental identification and robust optimization of spindle–bearing systems with reliability constraints

Effective vibration control and dynamic behavior management in the presence of parameter uncertainties are critical for high-speed motorized spindles. Although traditional robust design optimization minimizes dynamic response variability, it lacks explicit control over failure probabilities. To address these limitation...

Rotor notch optimization of interior permanent magnet synchronous motor considering manufacturing uncertainty

This study aims to reduce torque ripple and cogging torque in interior permanent magnet synchronous motors (IPMSMs) by optimizing a rotor-notch design robust to manufacturing tolerances. It seeks to balance performance and reliability using Six Sigma (6s) principles. A robust optimization framework is propos...

Parameter Robustness of Model Predictive Control in Multiphase Machine Drives: A Comprehensive Review

Multiphase machines offer low per-phase power stress and strong fault-tolerant capability and have therefore attracted substantial interest in both academia and industry. Model predictive control (MPC) is an advanced control approach that can improve the dynamic performance and efficiency of motor-drive systems. Howeve...

Minimization of the Dynamic Response of Induction Motors Using the Topology Optimization Method

Two-pole induction motors are widely used in industry due to their reliability and efficiency. However, these machines present significant challenges related to vibration, mainly caused by electromagnetic forces associated with the characteristic component at twice the line frequency (2×LF). This phenomenon may lead to...

Reliability modeling and simulation evaluation of a helicopter control system based on a digital prototype

As a core flight control actuator, the reliability of the helicopter control system directly affects the flight safety of the entire aircraft. Driven by the limitations of traditional physical prototype reliability tests—namely, lengthy cycles, high costs, and the inability to easily reproduce faults—along with the lac...

Performance Evaluation of Optimized Controllers for Electro-Hydraulic Actuator Systems Under Mismatched Disturbances

To address the precise tracking challenges caused by non-linearities and operation uncertainties in high-power-density electro-hydraulic actuators (EHA), this paper evaluates the performance of 3 distinct control schemes: a conventional Proportional-Integral-Derivative (PID) controller, a Modified Sliding Mode Control...
