In this paper, a novel Multivariable Sliding-mode Extremum Seeking (MSES) Proportional-Integral (PI) tuning method is proposed and its application is studied for torque control in a Permanent Magnet Synchronous Motor (PMSM). To this end, the stator three-phase currents are characterized by their maximum amplitude which directly controls the shaft torque. Hence, a PI controller is applied for controlling...
Perturbation-based extremum seeking (ES) is a non model-based approach to maximize or minimize the output of a dynamic system without requiring any explicit information about the dynamics of the system, steady state map, or the value of the extremum. In this work, perturbation-based ES is used to minimize power reflection from a cavity resonator in order to provide maximum accelerating field for particles...
In this work, an adaptive control of a three phase ac/dc converter is investigated. The classical vector control method has been extensively used for the control of the ac/dc converter in different applications but the design gains are highly dependent on the system parameters. We employed an adaptive PI control method to cope with the system uncertainties. The method relies on a third order model...
