Abstract. This paper deals with the tracking control design of an induction motor, based on input-
output linearization with magnetic saturation included. Magnetic saturation is accounted for by the nonlinear magnetizing curve of the iron core and is used i[r]

Standard squirrel cage induction motors are designed for single speed operation. If it is intended to use the capability of a drive to run a motor at speeds above its designed maximum, it is strongly recommended that the manufacturer is consulted first. Low speeds may c[r]

The SCIG, on the other hand, may start with the IG in motoring by fixing a positive torque reference to the machine-side converter to complement the unregulated torque contribution of the turbine, after the water gate is opened. The acceleration is fast, and the “synchronization” sequence is elimina[r]

Notions of indirect and direct vector control were introduced in the preceding paragraph and they ask for further clarification. These terms are related to the way in which orientation is achieved but they are not related to any specific choice of flux along which orientation is performed. Di[r]

Abstract. In this paper a novel scheme for vector control is presented that aims to improve some of
the weaknesses of the sensorless vector control. Among indirec[r]

The main components of the simulated plant are DC circuit, inverter, motor, process, and control. Two basic control schemes can be selected: torque or speed control.

The principal functions are a translator, which gen- erates the motor phase sequences, and a dual PWM chopper circuit which regulates the current in the motor windings. The translator generates three different sequences, selected by the HALF/FULL input. These are normal (two pha[r]

As there are always two voltage vectors which may be chosen for one given combination of C T and C Ψ this gives the possibility to control another quantity. Here the input phase angle is chosen as the two possible voltage vectors are always arranged on the sector boundaries of the co[r]

There are many methods of speed control of DC drives namely field control methods. DC motors provide high starting torque which is required for traction applications. In DC motor[r]
