| 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. |
