Simulation studies of three synchronous reluctance motor (SynRM) control strategies are presented: field-oriented (FOC), direct torque (DTC), and finite-set model-predictive (FS-MPC). FOC uses linear controllers pulse-width modulation to the fundamental components load voltages vectors. In contrast, DTC FS-MPC nonlinear wherein voltage vectors directly generated in absence a modulator. Theoreti...

Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

this paper presents an overview of model updating and particularly its application for updating of frame model. in this article a mathematical model of the frame was produced with finite element method. the frame was subjected to hammer modal testing. then the results of the modal testing were compared with those predicted with the model. this comparison revealed discrepancies between these two...

For the motion of distributed drive electric vehicles, this paper deigns a novel control strategy based on model predictive control, which can longitudinal and lateral simultaneously. Different with traditional strategies containing one vehicle controller four motor controllers, treats its in-wheel motors as object uses only to realize so that costs are reduced handling performance is improved....

the efficiency of induction motors decreases at light loads. efficiency optimizer control systemsadjust the motor flux value to achieve the best efficiency in a wide range of load variations. reduced fluxoperation has some other benefits such as power factor improvement and torque ripple reduction. the latter isan important issue in a direct torque controlled induction motor drive. in this pape...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
