Subject of this contribution is a novel PWM controlled inverter of the kW power range, feeding a multi- mass ultrasonic motor (MM-USM) via a LLCC-type filter. The system is designed in a way to reduce the total harmonic distortion of the motor voltage and to locally compensate for the reactive power of the motor. Operating a three- level inverter with PWM(More)
Model Predictive Control (MPC) is a very powerful and increasing popular control method. Due to increasing calculation power of state-of-the-art control hardware platforms and computationally efficient MPC approaches, MPC is already feasible for processes with small time constants as they are common in converter and drive control. In this paper, a(More)
