Parameter sensitivity of indirect universal field oriented controllers
PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 1994The universal field-oriented (UFO) controller was developed to decouple flux and torque in an arbitrary synchronous flux reference frame, realizing a high degree of generality which makes the UFO controller compatible with all existing field-oriented controllers, including indirect and direct field orientation.

Current measurement of digital field oriented control
IAS '96. Conference Record of the 1996 IEEE Industry Applications Conference Thirty-First IAS Annual Meeting, 1996This paper studies current measurement issues of all digital field oriented control of AC motors. The paper focuses on the effect of an antialiasing filter and also on the sampling of the fundamental components of the motor current. The antialiasing filter, which suppresses the high frequency component of the motor current, introduces cross coupling ...

Field-oriented control of saturated induction machines
IEEE Transactions on Energy Conversion, 1990A nonlinear, field-oriented model is described for saturated induction machines. The model is an extended version of the rotor-flux-oriented dynamic model developed by W. Leonhard (1985), which is valid under linear magnetic conditions and is used in a wide range of applications. The effects of main flux saturation are discussed.

Field oriented control of a synchronous drive
IEEE International Conference on Electric Machines and Drives, 2005., 2005Field oriented control (FOC) may be used for simple high-power synchronous drives, such as pumps and fans, to unify system with asynchronous drives. But distinction is strong influence of torque component of current on flux. Internal feedback in control object is investigated. This feedback becomes positive one in definite regimes. A simple addition in

Indirect Field Oriented Control for Induction Motor
2011 Fourth International Conference on Emerging Trends in Engineering & Technology, 2011Indirect Field Oriented Control (IFOC) is known to produce high performance in induction Motor (IM) drives by decoupling rotor flux and torque producing current components of stator current. The decoupling control between the rotor flux and the torque is no longer achieved in terms of stator current components this paper introduces a decoupled rotor ...

Field oriented control drives for naval mechanisms
IEEE EUROCON 2009, 2009In this paper, the authors propose the embracing of a solution regarding the implementation of the direct vector control in torque and flux on the induction motor with squirrel cage rotor for the electrical drive systems of the naval mechanisms. Through this is desired the replacement of the actual technical solution, at which for the drive of the ...

Controllable Dendritic Crystal Simulation Using Orientation Field
Computer Graphics Forum, 2018AbstractReal world dendritic growths show charming structures by their exquisite balance between the symmetry and randomness in the crystal formation. Other than the variety in the natural crystals, richer visual appearance of crystals can benefit from artificially controlling of the crystal growth on its growing directions and shapes.

Parameter insensitive controllers for field-oriented controlled induction machines
Proceedings of 5th International Conference on Power Electronics and Variable-Speed Drives, 1994The paper describes practical experiences of the use of a digital sliding mode controller for control of an inverter fed induction machine. It is shown that such a controller has several advantages in comparison to a conventional PI controller. Through linearisation of the nonlinear controller, the method of pole assignment can be used. The programming

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 ...

Dynamics of Vector Control and Field Orientation
1996Abstract The steady state analysis in Chapter 5 has been used to demonstrate the basic concepts of vector control and field orientation in both synchronous and induction machines. The underlying motivation in Chapter 5 was to obtain torque (and flux) control independent of motor speed.
