| Abstract |
Modern microcontrollers and DSP controllers especially ease due to their integrated peripherals the
implementation of closed-loop control for a.c. induction, synchronous and brushless d.c. motors. The
non-linear, time-variant behaviour and the discrete (switched) working principle of the switched
reluctance motor also demands the implementation of closed-loop speed and torque control on
microcontrollers and DSP controllers.
Although control algorithms totally differ between an a.c. motor and a switched reluctance motor, the
same plant parameters like rotor speed and position for example are necessary for optimum operation.
Based on the different control principles and the methods for measuring the electrical and mechanical
plant parameters of a switched reluctance motor, an ideal control unit will therefore be defined. This
device will be compared to several standard microcontrollers and DSP controllers to examine the
suitability of such integrated circuits for the control of switched reluctance drives. |
