Abstract :
The development of discrete sliding mode control for three-phase PWM converters with LCL filter is presented. This robust control method is investigated for the current control loop. Done in a discrete state space system, a feedforward feedback structure is utilized. A reference state trajectory and feedforward control in αβ coordinates, discrete integral SMC in dq coordinates are designed and analysed. Simulation and experimental results are shown.
