Static and dynamic directional stabilities are important features of an aircraft in design phase and to study transient response characteristics. Torsional pendulum, used to measure moment of inertia, has been employed to determine the method of finding directional stability of an aircraft because of a relation between moment of inertia and directional stability. Mathematical relation for moment of...
This paper deals with the speed and position estimation of interior permanent-magnet synchronous motor (IPMSM) and synchronous reluctance motor (SyRM) drives. A speed-adaptive full-order observer is designed and analyzed in the discrete-time domain. The observer design is based on the exact discrete-time motor model, which inherently takes the delays in the control system into account. The proposed...
