摘要: Fault Tolerant Control (FTC) systems are crucial in industry to ensure safe and reliable operation, especially of motor drives. This paper proposes the use multiple controllers for a FTC system an induction drive, selected based on switching mechanism. The switches between sensor vector control, sensorless closed-loop voltage by frequency (V/f) control open loop V/f control. Vector offers high performance, while is simple, low cost strategy with speed satisfactory performance. faults dealt failures, stator winding circuits, shorts minimum faults. In event compound faults, protection unit halts operation. detected using wavelet index. For novel Boosted Model Reference Adaptive System (BMRAS) estimate presented, which reduces tuning time. Both simulation results experimental drive show scheme be fast effective one fault detection, methods transition smoothly effectiveness system. also shown flexible, reverting rapidly back dominant controller if returns healthy state.
