Control of Synchronous Actuators

Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.

French and Lebanese engineers present the control laws of conventional synchronous motors, as distinct from induction motors. They cover problems and modeling synchronous motor controls; designs of optimal supply and synchronous motors torque control in the a-b-c and d-q reference frames; drive controls with synchronous motors; the digital implementation of vector control of synchronous motors; the direct control of a permanent magnet synchronous machine; synchronous machine and inverter fault tolerant predictive controls; characterizing control without a mechanical sensor in permanent magnet synchronous machines; and deterministic methods, convergence, and robustness in the sensorless control of permanent magnet synchronous machines.
