   Direct mean torque control with improved flux control
By J. Faßnacht; P. Mutschler [View]
[Download]

Abstract: This paper presents an improved direct torque and flux control algorithm for induction machines based on the Direct Mean Torque Control (DMTC). The new algorithm combines the high dynamic per-formance of a direct torque control method with a precise flux control. To achieve this the original DMTC algorithm is augmented by a third voltage vector if necessary and an improved flux controller is proposed. Experimental results show, that with this improved DMTC in conjunction with a 6th-order observer of the mechanical system, high frequency mechanical oscillations (400Hz ; 850Hz) can be successfully damped.

   Feedforward control of two mass servo systems for high speed response
By R. Nakashima; T. Tsuji; S. Kaku; H. Honda; R. Oguro [View]
[Download]

Abstract: This paper concerns with high precision and high speed control of a ball screw type linear motor. The control manner is necessarily a multi-rate sampling system. In this paper, in order to get the high speed response, the relatively slow sampling rate for a feedfoward control command, while the high sampling rate for a feedback control. This paper show how to design the feedfoward and feedback control. Effectiveness is verified by experiments.

   Cylindrical linear electric drive of industrial mechanisms
By R. Rinkevièienë; A. Juozas Poðka [View]
[Download]

Abstract: The paper substantiates theoretical and experimental aspects used by the authors to develop and investigate linear electric drives with cylindrical linear induction motors. The example of employing such linear drives in the conventional high voltage circuit-breakers, in the circuit-breakers with separately controlled contacts and in the industrial continuous action furnace to push magnetic cores is presented.
