“…Most of these permanent magnet rotors consist of a half circle in which there is one pole on each side of it. State equation of brushless electric motor is as followings [11]: Since flux density in brushless electric motors is trapezoidal as Fig. 3, back electromotive force on stator windings and also electric torque are trapezoidal.…”

Reaction Wheel (RW) is the most popular actuator in the Attitude Control System (ACS) of satellites which has a significant role in performing satellite missions. Reaction wheel supplies the torque and the momentum that is required for satellite attitude control. The RW model which is used in the ACS simulations and FDI algorithms should be an accurate model. On the other hand, each physical module has a special role in the reaction wheel modeling. In this regard, based on elements in the internal structure of this actuator, a precise model of RW is presented. Furthermore, the proposed model of RW is more general and can be used in other types of RW. Moreover, in this paper proposed a new model of the reaction wheel for ACS simulation. The proposed model of RW is validated by a RealTime HIL test bed in the form of set point commands and profile command.Keywords-satellite attitude control, modeling reaction wheel, hardware in the loop, brushless electric motor, disturbance torques of bearing, static and dynamic imbalance

“…With nonlinear material, µ is function of flux density; it can be gotten from characteristic of BH-curve. If the electric scalar potential difference caused by the electric charges moving in the magnetic field is neglected, the gradient of the electric scalar potential will be set to zero [6]. For the 2D FEM model, the influence of the end effects are neglected, thus the electric field strength E, the vector magnetic potential A and the current density of source J s have only component in the z-direction, so E=E z e z , A=A z e z , and J s =J z e z .…”

This paper presents a concept in the form of a flow chart for analyzing and designing permanent magnet machine by finite element method (FEM) including rotor motion. According to our flow chart, geometry modeling will automatically be made by script. Therefore, it is easy in changing design parameters. Two programs have been developed based on the proposed flow chart, one for static solution and the other for nonlinear transient solution. The magnetic saturation model and solvers have been discussed. These ensure that the FEM program is convergent and runs faster during high saturation. The influence of slot opening on the magnetic field and internal voltage is investigated. Results are used to select slot opening for maximizing internal voltage.Index Terms--Concentrated windings, design flow chart, magnetic saturation, permanent magnet machine, FEM, slot opening.

An intelligent and efficient closed-loop simulation system without any hardware is proposed for AC servo system. According to the characteristics of AC servo system and its control processor, the code executing platform combined with the reverse Polish notation algorithm is developed. To gain the accurate simulation results, the discrete motor model and IPM model are built to deal with the dead-time. Based on the simulation system, parameter identification can be implemented and control parameters can be optimized by using the exhaust algorithm. The parameters obtained by the simulation system were successfully applied to an experimental system, and the favorable control performance was achieved.control code, closed-loop simulation, discrete model, parameter identification, parameter optimization
