Field-oriented control (FOC) is a preferred control method for induction motors. The purpose of FOC is to guarantee perfect dynamic and steady performance of induction motors, but there is cross-coupling between dq current components, which impairs the characteristics of response. Therefore, a decoupled current control strategy using internal model based on active disturbance rejection control (ADRC)...
The goal of life extending control is to trade off the handling qualities of UH-60 Black Hawk helicopter and the service life of main rotor shaft. An increase in the service life results in enhanced safety and reduction in maintenance costs. Different from simply minimizing the amplitude of rotor shaft bending stress cycles, a real-time nonlinear fatigue crack growth model is included in the analysis,...
