Cogging torque makes great attribute to the torque ripple and noise of permanent magnet motor. The causes to produce cogging torque are discussed in this paper. The cogging torques of two PM motors is computed by finite element analysis. Computed results show the effectiveness of pole-slot-pairing method to reduce ideal cogging torque. While in practical motor, there may be some defects caused by manufacture, such as magnet performance discrete, and the evaluation of stator inner surface. These defects can cause non-ideal cogging torque. Such cogging torque is quantificationally analyzed by finite element analysis.

The frequency responses of the common-mode (CM) electromagnetic interference (EMI) noise source for a switch-mode power supply is approximated in this paper. The amplitude of the equivalent Norton current source and the shunt admittance for the CM noise model are obtained by numerical analysis. The calculated frequency responses are valid almost in the entire measured frequency range. The CM filter design can be facilitated by using the obtained frequency responses. It is verified that the results are satisfactory.

A relatively accurate analytical expression of the magnetic levitation force for an induction-type bearingless motor is proposed in this paper with the eccentricity in the location of stator and rotor taking into consideration, and its computation accuracy is verified by ANSOFT, an electro-magnetic field analysis software of electrical machines. Applying this analytical levitation force model, the real-time observation of magnetic levitation force is realized, the closed-loop control of levitation force is then implemented on the basis of air-gap-flux-oriented decoupling control system of the bearingless motor. Simulation study verifies the effectiveness of the approach in improving the static and dynamic performance of an induction-type bearingless motor.

Switch mode power supplies have been controlled using different control algorithms like PID control, current mode programmed control etc. Many control tools were used to implement these control techniques e.g. analog operational amplifier, microprocessor. This paper focuses on using a new control tool called dSPACE/sup /spl trade// for controlling the switch mode power supply. Programming the control circuit via MATLAB/Simulink/sup /spl trade// can be made. The prototype of the basic three converters buck, boost, and buck-boost can be controlled by the simulation model via real time hardware. Buck-boost converter was chosen as our prototype converter. The sliding mode control (SMC) was chosen as a control algorithm in MATLAB/Simulink/sup /spl trade// for controlling the buck-boost prototype model. The reason behind choosing SMC is that it is an efficient control and simple to implement in MATLAB/Simulink/sup /spl trade//. The paper shows that the control algorithm represented by SMC in MATLAB/Simulink/sup /spl trade// and using the dSPACE/sup /spl trade// as control toolbox is able to control the prototype model.

The paper describes an analytical modelling technique for calculating the radial force on the rotor of a bearingless consequent-pole permanent magnet motor. The advantages of the technique is the flexibility with which it is applied so that it is used to identify vibration components and also calculate the force in a variety of situations when the rotor is not centred in the bore, i.e., when the rotor has either dynamic eccentricity, static eccentricity or when the rotor is vibrating in the stator bore. It also allows the force to be calculated with a varying load or even with load imbalance. The paper studies the effects of winding design and gives a qualitative comparison to the force calculated using 2D finite element analysis under different loads.

This paper describes a method to improve the production rate for a magnetizer machine by modifying its circuit configurations. A resistor was put in series with the recovery diode in order to bring out part of the heat from the magnetizing fixture. It also reduces the discharging time of the inductor. The branch of the recovery diode in series with the added resistor was moved so that they were in parallel with the discharging capacitor instead of parallel with the magnetizing fixture. It provides a discharging route for the capacitor which was charged reversely when the inductor was discharging.

In order to realize high performance control of matrix converter fed induction motor drive system, a combined controller is proposed to implement both space vector modulation and direct field oriented control. Space vector modulation is employed to regulate the input/output sinusoidal currents of matrix converter. The direct field oriented control technique is applied on the drive system to ensure the good performance of induction motor. Using this controller, it is possible to combine the advantages of matrix converter with the advantages of vector control technique. Simulation and experimental results have demonstrated the feasibility and effectiveness of the proposed controller.

The application of a new complementary gating scheme for the full bridge DC-to-DC PWM converter is proposed. The proposed gating scheme results in different types of transitions and only one ZVT circuit is required to achieve ZVS for all the switches for a wide variation in the load current. Detailed operation and analysis of the converter using equivalent circuits is presented. Design procedure is illustrated using a 500 W DC-to-DC converter example. PSPICE simulation and experimental results are presented for the designed converter to verify the theory.

This paper is concerned with the control of bifurcation and chaos in voltage controlled buck converter, which is a piecewise-smooth dynamical system. By taking the advantage of the OGY method, a two-parameter control strategy is put forward. It prevents the system from losing stability due to the error in obtaining the unstable periodic orbit (UPO) while OGY method is applied. An application to a simple voltage controlled boost converter is also presented.
