   HIGH-SPEED PC-BASED CAD FOR MOTOR DRIVES
By D. A. Staton; M. I. McGilp; T. J. E. Miller; G. Gray [View]
[Download]

Abstract: Following on from an EPE-91 paper [1] describing high-speed integrated CAD environment for switched reluctance and permanent-magnet brushless DC motor drives, this paper reports the extension and development of these design techniques in two selected areas: 1. - the design and modelling of DC commutator motors and their drives; 2. - the dynamic modelling of the complete control system of switched reluctance motors over long periods. As in the previous paper, the software-engineering aspects are explained and emphasized, as these are crucial for the improvement in engineering productivity during the design process. However, the paper also describes new work in the area of electronic control of the switched-reluctance motor, particularly in relation to the stability and dynamics.

   USE OF AN EXTENSION OF THE PARK'S TRANSFORMATION TO DETERMINE CONTROL LAWS APPLIED TO A NON-SINUSOIDAL PERMANENT MAGNET SYNCHRONOUS MOTOR
By Damien Grenier; Jean-Paul Louis [View]
[Download]

Abstract: An extension of the analytic Park's modelling to the case of non-sinusoidal permanent magnet synchronous motor is proposed. This modelling permits us to analyse the classica! 120° voltage control law and to deduce new vector control laws in "abc" and "dq" frames, which allow best dynamic and steady state behaviours.

   POSITION CONTROLLED PERMANENT EXCITED SYNCHRONOUS MOTOR WITHOUT MECHANICAL SENSORS
By B.-J. Brunsbach; G. Henneberger; Th. Klepsch [View]
[Download]

Abstract: The pole-position and the rotor speed of a permanent excited synchronous machine can be estimated by a Kalman filter using only the voltages and currents of the machine. This replacement of the mechanical sensors by a Kalman filter reduces the volume of the motor and increases the sturdiness of the drive. In this paper the application of a sensorless operating synchronous machine using a Kalman filter in an indirect position controlled drive system is described. The actual position, necessary for the position control, is determined indirectly by converting the estimated pole-position to the load side. Such a drive system operates without any mechanical sensor. By impressing a current in the direct-axis of the motor the Kalman filter can also estimate the pole-position of an unloaded drive at standstill. Practical tests verify this method. The given practical results prove, that the application of a sensorless drive in an indirect position control is possible. A realization of such a sensorless position control in a robot with integrated drives is planed.
