This study presents a novel means of designing a simple and effective torque controller for Permanent Magnet Synchronous Motor (PMSM). The overall stability of the system is shown using Lyapunov technique. The Lyapunov functions used contain a term penalizing the integral of the tracking error, enhancing the stability. The tracking error is shown to be globally uniformly bounded. Simulation res...

For permanent magnet linear synchronous motor (PMLSM) working at trapezoidal speed for long time, high thrust brings temperature rise, while low limits dynamic performance. Thus, it is crucial to find a balance between rise and In this paper, velocity planning model of the PMLSM based on electromagnetic-fluid-thermal (EFT) field proposed obtain optimal performance under limitation. model, windi...

This paper presents the optimal mechanism design and dynamic analysis of a prototype 3-leg 6-DOF (degree-of-freedom) parallel manipulator. Inverse kinematics, forward kinematics, inverse dynamics and working space characterizing the platform motion are derived. In the presented architecture, the base platform has three linear slideways individually actuated by a synchronous linear servo motor, ...
