Microcomputer based sliding regime discrete control for synchronous AC motors

The basic ideas are presented to design discrete algorithms to calculate the mechanical or electrical variables, not measured but estimated, to control electric motors in mechanical systems. The main objective of this article is to simplify the algorithms using a linear discrete time model without any limitation on the variables and reduce the computing capacity requirements of the controller. The limited references, based on the discrete sliding mode for the exception of the influences of variable limitations, are proposed and designed. The main advantage of the driver presented in this article is that a large control error does not cause any problems. In that case, the system always works in an area without limitations. The original position and rotational speed observation algorithms are designed for the permanent external magnet of synchronous motors. A computer simulation was carried out and the results are presented, which show high dynamic accuracy.
