[Digital control of low power permanent magnet synchronous actuators]

High performance motion control with permanent magnet synchronous actuators needs complex control strategies. These control strategies lead frequently to algorithms requiring powerful microprocessors for their digital implementation. In this paper, we consider an approach of the control of small power permanent magnets synchronous actuators which allows to design and to implement control algorithms requiring only a reduced computation power, while maintaining satisfactory static and dynamic performance and a good insensitivity to perturbations and parameter uncertainties.
