| Abstract |
In this paper, a new variable structure position control law for a DC motor is proposed. The algorithm
based on a time-varying switching line guarantees the existence of a sliding mode since the beginning
of the shaft motion. Indeed, the surface is initially designed to pass through the initial representative
point and subsequently moved towards a predetermined desired surface by shifting. By this mean, the
reaching phase is eliminated and the motor behaviour is insensitive to unknown mechanical
configuration changes. The algorithm has been tested in simulation and the experiment has been
performed using a low-cost 16-bit microcontroller. An advanced test bed is used in order to evaluate
the robustness capacities of the proposed controller. |
