Computer-aided design of sliding mode control of permanent magnet synchronous motors

This paper deals with a methodology for computer-aided design (CAD) of sliding mode speed control of permanent magnet synchronous motors. The drive system is built around several components that have their own technology and multiple time-scales: electrical machine, power semiconductors, and control circuits from the firing sequences to the different regulators. By using digital simulation as a reliable way, a methodology for CAD has been implemented to test the different dynamics of the drive system. In this paper the sliding mode control is applied in all regulation loops from speed regulation until the minimization of harmonics introduced by the line converter
