Abstract :
A completely digital control concept for a synchronous servodrive is presented. The hardware consists of a pulsewidth-modulated (PWM) inverter and a microcontroller with peripheral components for state-value measurements and set-value output. The derivation of a mathematical model of the PM synchronous servodrive is shown. A cascaded state feedback controller (which consists of a position state feedback controller with an inner-current control loop) is introduced. Two different types of current controllers are compared
