WebNewton’s Second Law for Rotation. If more than one torque acts on a rigid body about a fixed axis, then the sum of the torques equals the moment of inertia times the angular acceleration: ∑ i τ i = I α. 10.25. The term I α is a scalar quantity and can be positive or negative (counterclockwise or clockwise) depending upon the sign of the ... WebApr 14, 2024 · The safety of direct torque control (DTC) is strongly reliant on the accuracy and consistency of sensor measurement data. A fault-tolerant control paradigm based on a dual-torque model is proposed in this study. By introducing the vector product and scalar product of the stator flux and stator current vector, a new state variable is selected to …
