This paper presents a position sensorless drive of a brushless dc motor with a sinusoidal flux distribution. The estimation of position and emf is performed by using the integration of the current differences between the actual motor and model. The estimation speed is calculated by the differential calculus of the estimated position. The stability of the proposed algorithm and the design of the estimation gains are explained and it is shown that the parameter differences do not give serious effects on the estimation characteristics.In the experimental results using a 6-pole 1.2kW test motor, the speed control range from 35 to 1500rpm is obtained. To verify the proposed algorithm, the estimation and speed control characteristics are shown. Furthermore, the starting characteristics of the motor from arbitrary rotor position are shown.

DC-DCコンバータやDC-ACインバータに広く用いられているロイヤー回路は,回路構造が簡単にもかかわらず回路解析が面倒なため,従来,スイッチング時間や電力損失の評価はほとんどなされていなかった.本論文は比較的低負荷時のロイヤー回路の動作解析を行ったものである.回路素子のモデルは磁心のB-H特性は平行四辺形の折線で近似し,トランジスタは電荷蓄積効果を考慮した Ebers-Mollのモデルを用いた.又,計算方法は状態推移法を使用した.計算機によるシミュレーションの結果は実用上十分な精度であることを実験によっても確めた.

PWM control is promising to achieve a unity power factor and to improve the input current distortion in a high performance current-source three-phase AC/DC converter system. In contrast to the voltage-source converter, the LC filter connected between the source and the converter may cause an LC resonance both in steady and transient states. Many reports have been published to improve the current distortion in steady state and to suppress the current oscillation in transient state of the current-source PWM converter by using the feedback control.This paper gives an analysis of the transient oscillation of the filter voltage and current, and proposes a simple open-loop suppression method by using the rate limiter of the input current reference. Furthermore, the design rule of the LC filter for the suppression control of the transient oscillation is described. The effectiveness of the proposed approach has been verified by experiments.

This paper presents a torque ripple reduction design of a concentrated-winding IPMSM with a new flux barrier for saliency-based sensorless drives. The proposed IPMSM is designed for use in general-purpose sensorless industrial drives. In order to reduce torque ripple, its rotor employs a V-shape-magnet arrangement and circular flux barrier which is placed at the center of a rotor yoke between N- and S-poles. A 45-Nm 5.5-kW IPMSM is manufactured as a prototype in order to confirm the design validity, and experimental studies using the prototype demonstrate the expected drive characteristics and validate the proposed design procedure.

This paper presents a position sensorless drive of a salient-pole brushless dc motor with a sinusoidal flux distribution. The algorithm is based on the estimation of back emf which is identified by the errors between the actual and estimated currents. Since the direction and amplitude of the estimated emf correspond to the rotor position and speed respectively, the position and speed can be estimated. The stability of the estimation and the design of the estimation gains are examined.The proposed algorithm were verified by using a 6-pole, 200W, 3000rpm test motor. In the results, the sensorless speed control range from 50rpm to 4000rpm under 0_??_100% load was obtained. The estimation algorithm is stable for any position error and any emf error.

The authors already proposed the new control scheme of the PWM converters where the control scheme was performed on the estimated voltage and phase of the source, thus eliminating the voltage sensor.The paper deals with a stability problem of a sensorless PWM converter control. Under consideration of the parameter error, the stability analysis of the proposed control is examined. In addition to that, a design procedure of the estimation gains is also examined. For the stable starting of the system, the initial estimation of the amplitude and phase angle of the source voltage is proposed.The effectiveness of the theoretical stability and estimation gain design has been confirmed by experiments.

In motion control applications, servo drive systems have widely applied to various load systems with complicated mechanisms. A robot arm with flexible joints is one of typical examples and it forms multi-mass resonant systems which generate mechanical vibration. Since such vibration gives tracking errors in motion and/or increase of settling time, the vibration suppression is indispensable to achieve the high performance robot arm motion. Many schemes such as model-based feedforward control and modern control theory-based feedback control have been proposed to overcome those problems.This paper presents a new feedforward control scheme using optimal control command shaping to suppress the resonant vibration in robot arm motion. By analyzing characteristics of the conventional position controller with the S-shaped position command, an optimal command design can be examined to eliminate the resonant vibration. Based on these analyses, a new command shaping algorithm is proposed. The proposed feedforward scheme can obtain the same vibration suppression characteristics as those by the conventional feedback schemes, regardless of the simple input position command shaping. Experimental results with a prototype show an effectiveness of the proposed control.
