Abstract Abstract. A detailed mathematical model of a DC servo drive is established and validated by measurements. Due to battery power supply, a pulse-width modulated (PWM) voltage signal, and a microcontroller with low sampling rate (typical for embedded systems) a comprehensive switched non-linear description results. Linear and sliding-mode controllers (SMC) are de-signed for the drive. Robustness with respect to parameter variations and measurement noise is investigated by simulation. In contrast to many other reports the linear controller outper-forms the SMC because of the given restrictions in control input and sampling time. 1
