This paper considers the control problem of a robotic manipulator with separately excited dc motor drives as actuators. An innovative method is proposed which achieves robot speed-control requirements, with simultaneous minimization of total electromechanical losses, while the drives follow the desired speed profiles of the robot joints under various loads(More)
The objective of this paper is to give an insight about the development of a fuzzy logic efficiency control system which is incorporated to a standard adjustable speed drive control (i.e. Indirect Vector Control) in order to improve the online efficiency in Permanent Magnet Synchronous Motor (PMSM) drives for both transient and steady state operation. The(More)
This work contributes to the development of control techniques for the drive systems of battery-powered electric vehicles, hybrid electric vehicles HEVs, 1<sup>st</sup> by introducing the design of a new motor efficient controller, in order to improve the energy efficiency of electric motors drives in HEVs and 2<sup>nd</sup> to achieve a fast torque(More)
