Advanced Healthcare Materials, EarlyView.This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Teaching Field Oriented Control using Animation
2021 17th Conference on Electrical Machines, Drives and Power Systems (ELMA), 2021Teaching the principles of control of electrical machines is a tedious job. Especially the required knowledge that has to be transmitted to the student is large, before a complete overview of the whole topic can be made. Also a solid background in both electrical machine dynamic behavior as well as in control theory is required for the student, before ...

The universal field oriented controller
IEEE Transactions on Industry Applications, 1994This paper synthesizes and develops a universal field oriented (UFO) controller for induction machines. The UFO controller decouples flux and torque in an arbitrary flux reference frame. Due to its high degree of generality the UFO controller lends itself to be fully compatible with all existing field oriented controllers, indirect as well as direct ...

Field Oriented Control of Synchronous Machines
IETE Journal of Research, 1991Although field orientation in induction machines is only 20 years old, the corresponding concept in synchronous machines dates back almost 60 years to the days of the thyratron tube. After a brief historical review, the basic theory of synchronous machine field orientation is outlined.

Sensorless field oriented control using common mode currents
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002A simple sensorless field oriented control technique of an induction motor drive is presented, that estimates the angular frequency of the main flux from common mode currents. The proposed technique is effective at any load level and any speed, ranging from zero to rated value and beyond, in the flux weakening region.

Slip frequency detection for indirect field oriented control drives
Conference Record of the 2001 IEEE Industry Applications Conference. 36th IAS Annual Meeting (Cat. No.01CH37248), 2002The paper presents a new technique to detect the slip angular frequency in induction motor drives based on indirect field oriented control. According to the proposed technique, the slip frequency is calculated by processing the effects exerted by an additional high frequency signal on the zero sequence stator voltage.

Induction Motor Control using Modified Indirect Field Oriented Control
2018 8th IEEE India International Conference on Power Electronics (IICPE), 2018This paper proposes the speed control of induction motor using modified indirect field oriented control (MIFOC). MIFOC scheme is based on the control of active and reactive power to regulate desired speed and torque of induction motor. The flux and torque estimation is not required in proposed scheme which reduces the complexity and ripples as compared

A neural network controller for indirect field orientation control
IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002This paper presents the design of a neural network controller for the stator current command in an indirect field oriented system. A particular three layer neural network structure is studied in some detail. This neural network controller has two outputs, stationary frame q and d axis current commands i/sub qs//sup s/ and i/sub ds//sup s/. The input to

Fuzzy supervisory control of field oriented controlled AC drives
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002The problem of setting an optimum flux reference for indirect vector controlled induction motors is addressed. The flux reference is generated using a fuzzy logic supervisor (FLS) which minimizes the power input to the motor in steady-state speed operations. The FLS is based on a simple search method.

Principles of Vector Control and Field Orientation
1996Abstract In this chapter the basic concepts of torque control and field orientation are introduced based on steady state considerations for both synchronous and induction machines. A basic set of three requirements which enable direct control of machine torque production is developed and used to illustrate the type of controller needed ...
